In this case,1,3,4-trimethyl-5-ethyl-uracil(m.p.99-100°)was similarly isolated.

4-Methyl-2,6-dichloropyrimidine was prepared by heating 4-methyl-uracil with phosphorous oxychloride in the presence of phosphorous pentachloride; and it boiled at 97° at 7 mm, at 102° at 10 mm, or at 113° at 13 mm. 4-Methyl-2,6- dichloropyrimidine reacted with sodium methoxide in anhydrous methyl alcohol, forming 4-methyl-2,6- dimethoxy-pyrimidine, which was isolated by ether extraction and pnrified by vacuum distillation. Pure 4-methyl-2,6-dimethoxy-pyrimidine boiled at 85-87° at 7 mm, or at 103° at 13 mm, and melted at 62-65°. It was recrystallized from petroleum ether, m.p. 65-66°. In the above reaction, there was isolated a white solid, suspending in the ethereal solution and being collected separately. This white solid, considered as a by-product, was dissolved in hot water and acidified with acetic acid, whereupon it separated in needles. After recrystallization from water, it melted at 201-202°. It was tentatively assigned to be 4-methyl-2-methoxy- uracil. Further, 2,6-dialkoxy-pyrimidines were prepared similarly as 4-methyl-2,6-dimethoxy- pyrimidine: 4-Methyl-2,6-dichloropyrimidine reacted with sodium ethylate in anhydrous ethyl alcohol, forming 4-methyl-2,6-diethoxy-pyrimidine, which boiled at 110°/11 ram. 4-Methyl- 2,6-dichloropyrimidine was treated with sodium n-propoxide in normal propyl alcohol, forming 4-methyl-2,6-di-n-propoxy-pyrimidine, which boiled at 120°/5 mm. 4-Methyl- 2,6-dichloropyrimidine reacted with sodium iso-propoxide in isopropyl alcohol, forming 4-methyl-2,6-di-isopropoxy-pyrimidine, which boiled at 103°/3 mm. The action of sodium n-butoxide in normal butyl alcohoI upon 4-methyl-2,6-dichloropyrimidnie gave 4-methyl- 2,6-di-n-butoxy-pyrimidine, which boiled at 147-148°/5 mm. The action of sodium isobutoxide in isobutyl alcohol upon 4-methyl-2,6-dichloropyrimidine gave 4-methyl-2,6- isobutoxy-pyrimidine, which boiled at 132-133°/6 mm. The action of sodium isopentoxide in isopentyl alcohol upon 4-methyl-2,6-dichloropyrimidine gave 4 methyl-2,6-di-isopentoxy- pyrimidine, which boiled at 145-146°/3 mm. 4-Methyl-2,6-dichloropyrimidine reacted with sodium benzoxide in benzyl alcohol, giving 4-methyl-2,6-dibenzoxy-pyrimidine, which boiled at 231°/6 mm. 4-Methyl-2,6-dimethoxy-pyrimidine was heated in a sealed tube at 330-350°, giving the completely rearranged isomeric compound, 1,3,4-trimethyl-uracil, which was purified by vacuum sublimation at 130° at 10 mm and then by recrystallization from 95% alcohol. The latter melted at 107-109°. Nevertheless, 4-methyl-2,6-dimethoxy-pyrimidine was dis- solved in methyl iodide, and kept at room temperature in the dark with occasional shaking; whereupon the partially rearranged product, 2-oxy-3,4-dimethyl-6-methoxy-pyrimidine, gradually separated out. After recrystallization from absolutealcohol, it melted at 134-135.5°. Its structure was established as follows: Pure 2-oxy-3,4-dimethyl-6-methoxy-pyrimidine was heated with dilute hydrochloric acid for one hour; whereupon 3,4-dimethyl-uracil, m.p. 220-221°, separated out. This partially rearranged product, 2-oxy-3,4-dimethyl-6-methoxy- pyrimidine was heated at 335-350° and was again transformed into its stable and completely rearranged modification, 1,3,4-trimethyl-uracil, which was purified by vacuum sublimation and then recrystallization from 95% alcohol. The latter melted at 109-110°.
