Procedure

4 g of 4-[2-(N-benzyl-N-methylamino)ethyl]-1-methyl-8-chloro-6-phenyl-4H-s-triazolo[4,3-a][1,5]benzodiazepin-5-one in 100 ml of ethanol containing 0.4 g of Raney nickel is hydrogenated at 50 p.s.i. hydrogen pressure until 0.0085 moles of hydrogen is absorbed. The suspension is filtered and the filtrate is evaporated. The residue is triturated with a small amount of cold ether and the title compound is filtered off and dried.
