o-Bis (β-chloroethyl)-aminomethyl-phenylalanine dihydrochloride (I, AT-581) was re- ported to possess significant antitumour activities. Furthermore, in view of the fact that compounds carrying a nitro group in the benzene ring show invariably higher antitumour activity as compared with the corresponding unsubstituted ones and that the electro- negative groups such as nitro can deactivate the chlorine atoms of the mustard grouping, thus decrease its toxicity, the authors synthesized 2-bis-(β-chloroethyl)-aminomethyl-5-...

o-Bis (β-chloroethyl)-aminomethyl-phenylalanine dihydrochloride (I, AT-581) was re- ported to possess significant antitumour activities. Furthermore, in view of the fact that compounds carrying a nitro group in the benzene ring show invariably higher antitumour activity as compared with the corresponding unsubstituted ones and that the electro- negative groups such as nitro can deactivate the chlorine atoms of the mustard grouping, thus decrease its toxicity, the authors synthesized 2-bis-(β-chloroethyl)-aminomethyl-5- nitro-phenylalanine(IV) in which a nitro group was introduced into the benzene ring of AT-581. Besides, 2-bis(β-chloroethyl)-aminomethyl-4-nitrotoluene(IV) was also synthe- sized. 2-Methyl-5-nitrobenzyl chloride (VII) was condensed with diethyl formamido-malo- nate to give diethyl 2-methyl-5-nitrobenzyl formamido-malonate (VIII), and the latter was readily converted to diethyl 2-bromomethyl-5-nitrobenzyl formamido-malonate(X) by N-bromosuccinimide in the presence of a small amount of dibenzoyl peroxide in anhydrous carbon tetrachloride. Treatment of X with diethanolamine afforded diethyl 2-bis(β- hydroxyethyl)-aminomethyl-5-nitrobenzyl formamido-malonate(XI), which was then chlorinated with thionyl chloride in dichloromethane to give the chloride (XII),and the desired product (IV) was obtained by the hydrolysis of XII with concentrated hydro- chloric acid. When compound VII was first treated with diethanolamine and then with thionyl chloride, compound VI was obtained.

The synthesis of m—Cresol from o—toluic acid by air oxidation was studied in a 1 liter reactor under vigorous stirring conditions in order to eliminate film resistances. The varitaions of the composition of the reactor liquid and quantities of overhead products with respect to time were determined. A mechanism and a kinetic model of the reaction have been proposed. The activation energies and frequency factors of the corresponding elementary reactions were obtained in an interval of 195 to 215℃. and various factors which affect the rate and yield of m-csesol were thoroughly analyzed The results of this study may serve as theoretical guidelines for determination of proper technological conditions of the reaction.
