Reaction Steps

4 g of 2-[2-(N-benzyl-N-methylamino)ethyl]-8-chloro-6-phenyl-1H-s-triazolo[4,3-a] [1,5]benzodiazepine-1,5-dione in 100 ml of ethanol containing 0.4 g of 5% palladium on charcoal is hydrogenated at 50 p.s.i. hydrogen pressure until 1 molar equivalent 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.
