摘要

New cpds. of formula (I): (where R1 is halogen or NO2, R2 is opt. halo-substd lower alkyl or dialkylaminoalkyl, R3 is H or halogen, R4 is H, opt. carboxy- or alkoxycarbonyl-substd. aliphatic acyl, or opt. halo-substd. aromatic acyl) and their salts have sedative, tranquillising, muscle-relaxant, anxiolytic and anticonvulsant activity. They can be prepd. e.g. by reacting a 1-R2-5-(O-R3-C6H4)-7-R1-2H-1, 4-benzodiazepin-2-one with HCHO in the presence of a base to give (I, R4 = H), which is opt. acylated.
