Synthesis of 4 alkyl 3,4 dihydronaphtho[2,3 f]quinoxaline 2,7,12 (1H) triones and 3 alkyl 5 arylamino 2 chloromethyl3H anthra[1,2 d]imidazole 6,11 diones based on reactions of 1 amino 9,10 anthraquinones with chloroacetyl chloride A method was developed for the synthesis of 4 alkyl 3,4 dihydronaphtho[2,3 f]quinoxaline 2,7,12 (1H) triones starting from 1 chloroacetylamino 2 halo 9,10 anthraquinones and pri mary and secondary amines. The reactions of 1 amino 2 alkylamino 9,10 anthraquinones with chloroacetyl chloride afforded 3 alkyl 5 arylamino 2 chloromethyl 3H anthra[1,2 d] imidazole 6,11 diones. The reaction products contain chloroalkyl groups, which can undergo further modifications.
