Neurotropic and Psychotropic Agents. VI. 1-Alkoxymethyl-1, 3-dihydro-2H-1, 4-benzodiazepin-2-ones

1-Alkoxymethyl-1, 3-dihydro-2H-1, 4-benzodiazepin-2-ones (II) were prepared by two methods : one was direct alkylation of 1, 4-benzodiazepin-2-ones (I) with alkoxymethyl chlorides and the other was via 2-[N-(alkoxymethyl) phthalimidoacetamido] benzophenones (IV) which were prepared from the corresponding 2-(phthalimidoactamido) benzophenones (III) and alkoxymethyl chlorides. Certain compounds prepared had comparable activity to diazepam and chlorodiazepoxide in taming and anticonvulsant tests in mice.
