Procedure

A mixture of 0.31 g. of 55% sodium hydride-mineral oil dispersion and 0.65 g. of N-(2-chloroethyl)piperidine hydrochloride in 25 ml. of dry dimethylformamide is stirred at room temperature for 0.5 hours. To the mixture is added 0.40 g. of 4,9-dihydro-4-methyl-10H-thieno[3,4-b][1,5]benzodiazepin-10-one and stirring is continued for 18 hours. The reaction mixture is cooled, quenched with water and extracted with chloroform. The dried chloroform extracts are concentrated to an oil which is purified by preparative thin layer chromatography (tlc) on silica gel with 10:1 benzene:methanol as eluent. The oil obtained is crystallized from hexane to give white crystals, m.p. 84°-88° C.
