Procedure
150.0 g of 6-amino-1-(4-chlorobenzyl)-5-nitroso-uracil were dissolved in 1.2 liters of formic acid at 70° C. and treated over 1.5 hours in portions with 76.84 g of zinc powder keeping the temperature between 75-80° C. After cooling to 55° C. the solid was filtered of, the residue resuspended in 800 ml of formic acid and the solid again filtered off. The filtrates were evaporated to a solid which was suspended in 350 ml of water. The solid was collected, washed and dried to give the title compound (149.1 g) as a white solid, mp 274-8° C.
