Abstract

Alkylation of 4-methyl-7(8)-nitro-2,3,4,5-tetrahydrobenzodiazepin-2-ones under phase transfer catalytic conditions or in dry acetone occurs only at position 1. The 5-alkyl isomers are obtained by reductive alkylation of 4-methyl-7(8)-nitro-2,3-dihydro-1,5-benzodiazepin-2-ones. The UV, IR, PMR, and mass spectra of the isomeric compounds are reported.
