실험 절차

A mixture of 5 mmol of 4,10-dihydro-4-(4-nitrobenzoyl)-5H-pyrrolo-[1,2-a]thieno[3,2-e][1,4]diazepine in 25 ml of ethyl alcohol and 25 ml of ethyl acetate containing 0.2 g of 10% Pd/C is hydrogenated for 5 hours. The reaction mixture is filtered through a pad of diatomaceous earth. The filtrate is concentrated in vacuo to a solid which is purified by flash chromatography on silica gel to give the desired product.
