Procedure

A mixture of 2.0 g of 3-[4-(1H-imidazol-1-yl)butyl]-6-nitro-2,4(1H,3H)-quinazolinedione, 1.0 g of 10% palladium-on-carbon catalyst and 200 ml of ethanol is shaken in a Parr hydrogenater under 45 pounds of hydrogen pressure until the hydrogen uptake is complete. The reaction mixture is heated to the boil and the catalyst is filtered off. The ethanolic solution is concentrated to a low volume and the desired product is recovered by filtration.
