Procedure

A mixture of 2 g of 9,10-dihydro-10-(4-nitrobenzoyl)-4H-pyrrolo-[1,2-a]thieno[2,3-e][1,4]diazepine in 20 ml of ethyl alcohol and 20 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 to give the desired product.
