Procedure

To a solution of 1.4 g (0.0035 mole) of N-[3-[6-phenyl)-11H-pyrido[2,3-b][1,4]benzodiazepine-11-yl]propyl]carbamic acid ethyl ester (from Example 29) in tetrahydrofuran under nitrogen gas was added 0.4 g (0.0105 mole) of lithium aluminum hydride and slight exothermic reaction occurred. The mixture was cooled to prevent overheating. The mixture was stirred at reflux temperature for 16 hr. Thin layer chromatography indicated only partial conversion had occurred. An additional 0.4 g (0.0105 mole) of lithium aluminum hydride was added and the mixture refluxed overnight. Thin-layer chromatography indicated the product was predominantly the title compound.
