REACTION OF 4-CHLORO-1-NITROBENZENE WITH o-SUBSTITUTED PHENYLACETONITRILES; SYNTHESIS OF 8-CHLORO-1-METHYL(AND METHYLTHIOMETHYL)-6-(2-SUBSTITUTED PHENYL)-4H-s-TRIAZOLO-1,4-BENZODIAZEPINES

Reactions of 4-chloro-1-nitrobenzene with 2-methyl-, 2-methoxy- and 2-(methylthio)phenylacetonitrile in methanolic potassium hydroxide gave mixture from which the excepted 3-aryl-5-chloro-2,1-benzisoxazoles Ia-c were isolated in addition to the 2H-indoles IIIa and IIIc and acridines VIII and IX.The 2,1-benzisoxazoles were reduced to the 2-aminobenzophenones XIIa-c which were transformed via the phthalimidoacetamido compounds XIIIa-c to 5-aryl-7-chloro-1,3-dihydro-1,4-benzodiazepine-2-ones XVa-c.Treatment with phosphorus pentasulfide led to the thiones XVIa-c which reacted in boiling butanol either with acetohydrazide or with (methylthio)acetohydrazide to give the title compounds XVIIa-c and XVIIIa-c.They showed only weak anticonvulsant, incoordinating and central depressant effects.
