Abstract

Preparation of 1,4-benzodiazepine-4-oxides (III), and novel intermediates (I) used in the manufacture thereof. where R3,R4, and R5 each = H, halogen, lower alkyl, lower alkoxy, cyano, CF3 or nitro; R6 and R7 each = lower alkyl or aralkyl; R8 = H, lower alkyl, lower alkenyl, lower alkynyl or lower cycloalkyl-lower alkyl. X = the anionic moiety of an acid addition salt. 'Lower alkyl' above denotes C1-C7 7-Chloro-2-methylamino-5-phenyl-3H-1,4-benzodiazepine 4-oxide and a (6-chloro-4-phenyl-2-quinazolinylmethyl)-trimethyl-ammonium-3-oxi- de salt whenever prepared by the methods specified. (I) as well as being useful intermediates in the preparation of pharmaceutically useful compounds (III), also possess useful cardioactive and antibacterial properties.
