4-Methyl-5-ethyl-2-thiouracil reacts with ethyl bromide in alcoholic solution in presence of sodium ethylate,forming 2-ethylmercapto-4-methyl-5-ethyl-uracil(m. p.141°),from which 2-ethylmercapto-4-methyl-5-ethyl-6-chloropyrimidine,boiling at 148-150° at 13 mm.,at 164-166° at 17 mm.,or at 180-185° at 25 mm.,is prepared according to the directions given by Johnson and Bailey.This chloro- pyrimidine reacts with sodium methylate in methyl alcohol forming 2-ethyl- mercapto-4-methyl-5-ethyl-6-methoxypyrimidine,boiling...

4-Methyl-5-ethyl-2-thiouracil reacts with ethyl bromide in alcoholic solution in presence of sodium ethylate,forming 2-ethylmercapto-4-methyl-5-ethyl-uracil(m. p.141°),from which 2-ethylmercapto-4-methyl-5-ethyl-6-chloropyrimidine,boiling at 148-150° at 13 mm.,at 164-166° at 17 mm.,or at 180-185° at 25 mm.,is prepared according to the directions given by Johnson and Bailey.This chloro- pyrimidine reacts with sodium methylate in methyl alcohol forming 2-ethyl- mercapto-4-methyl-5-ethyl-6-methoxypyrimidine,boiling at 152-154° at 11 mm., at 156-160° at 16.5 mm.,or at 162° at 22 mm.,and with sodium ethylate in ethyl alcohol forming 2-ethylmercapto-4-methyl-5-ethyl-6-ethoxypyrimidide,boiling at 139-140° at 5 mm.or 142-145° at 7 mm. 2-Ethylmercapto-4-methyl-5-ethyl-6-methoxypyrimidine interacts with chlorine with formation of 2-ethylsulfonyl-4-methyl-5-ethyl-6-methoxypyrimidine,m.p.45- 47°,in a yield of 81% of the theory.2-Ethylmercapto-4-methyl-5-ethyl-6-ethoxy- pyrimidine interacts with chlorine with formation of 2-ethylsulfonyl-4-methyl-5- ethyl-6-ethoxypyrimidine,boiling at 202-205° at 5 mm.or at 212-215° at 10 mm.,in a yield of 91% of the theory.2-Ethyl-mercapto-4-methyl-5-ethyl-6- chloro-pyrimidine interacts with chlorine with formation of 2-ethylsulfonyl-4- methyl-5-ethyl-6-chloro-pyrimidine,m.p.74-75.5°,in a nearly quantitative yield. 2-Ethylsulfonyl-4-methyl-5-ethyl-6-chloro-pyrimidine reacts with sodium methy- late in methyl alcohol,producing 4-methyl-5-ethyl-2,6-dimethoxypyrimidine,boil- ing at 123° at 15 mm.or 113-115° at 11 mm.;while 2-ethylsulfonyl-4-methyl- 5-ethyl-6-methoxypyrimidine reacts with sodium methylate in methyl alcohol, producing the same pyrimidine-dimethyl ether,boiling at 123° at 17 mm.2- Ethylsulfonyl-4-methyl-5-ethyl-6-ethoxy-pyrimidine reacts with sodium ethylate in ethyl alcohol in an analogous manner to form 4-methyl-5-ethyl-2,6-diethoxypyri- midine,which boils at 130° at 8 mm.4-Methyl-5-ethyl-6-methoxy-uracil,m.p. 194-195°,is produced by boiling 2-ethylsulfonyl-4-methyl-5-ethyl-6-methoxypyri- midine with 10% sodium hydroxide solution.Likewise,4-methyl-5-ethyl-6-ethoxy- uracil,m.p.179-180°,is produced by boiling 2-ethylsulfonyl-4-methyl-5-ethyl- 6-ethoxypyrimidine with 10% sodium hydroxide solution.The action of alcoho- lic ammonia upon 2-ethylsulfonyl-4-methyl-5-ethyl-6-chloropyrimidine at 100—105° gives 2-ethylsulfonyl-4-methyl-5-ethyl-6-aminopyrimidine,melting at 108—109°. 4-Methyl-5-ethyl-cytosine,m.p.296-298° or m.p.294°,is formed (i) by boiling 2-ethylsulfonyl-4-methyl-5-ethyl-6-amino-pyrimidine with 6 N hydrochloric acid and (ii) by heating 4-methyl-5-ethyl-6-methoxy-uracil with alcoholic am- monia at 120-140° for 18 hours.Thus,there are two new routes for synthesiz- ing 4-methyl-5-ethyl-cytosine,starting from 2-ethylmercapto-4-methyl-5-ethyl- uracil.Although these new methods involve one or two steps more than the old method described by Johnson and Bailey,who heated 2-ethylmercapto-4-me- thyl-5-ethyl-6-chloropyrimidine with alcoholic ammonia,producing the correspond- ing mercaptoaminopyrimidine,from which the ethylmercapto-group was removed by boiling with hydrochloric acid,they appear to be unique.

Two new crystalline glucosides have been isolated from the Chinese drug Chiu-pi-ying, which is identified as Ilex spp. and popularly used for curing malaria fever in Kwangsi province. They are provisionally named ilexanin A and ilexanin B respectively. The ilexanin A has the emperical formula, C_(19)H_(28)O_(10), m.p. 194°[α]_D~(31)—24°, and a crystalline acetyl derivative, C_(19)H_(22)O_(10)(CH_3CO)_6, has been prepared. It contains two methoxy groups. When hydrolysed with 5% sulphuric acid, it gives amorphous aglycone and glucose.The ilexanin B has the emperical formula, C_(33)H_(54)O_(10), m.p. 215—217°, [α]_D~(31)+13.3°, and forms a crystalline acetyl derivative, C_(33)H_(47)O_9(CH_3CO)_5. During hydrolysis with 1% methanolic hydrogen chloride, it gives a crystalline aglycone, C_(27)H_(42)O_4, m.p. 254°, and[α]_D~(31)+102°. Owing to losing one molecule of water in acetylation and hydrolysis, it seems that the acetylated product and aglycone of the ilexanin B have been converted into anhydrous compounds. The presence of a new double bond in each of these anhydrous compounds is confirmed by color test, forming a yellowish or brownish tint with tetranitromethane in chloroform solution. The sugar part of ilexanin B is glucose which is identified by its osazone.
