To 5-(4-methyl-4-nitropentylidene)hydantoin (3.15 g, 13.9 mmol) were added methanol (60 ml) and water (10 ml), and the mixture was reduced by the addition of palladium-carbon (2.2 g) and hydrogen. After the reaction, palladium-carbon was filtered off and the residue was concentrated to dryness. Decantation with water and dichloromethane gave 5-(4-methyl-4-nitropentyl)hydantoin (1.1 g).
