Reaction Steps
To 1-(2-cyano-acetyl)-1-cyclopropyl-3-(2-fluoro-4-iodo-phenyl)-urea 74 (192 g) were added water (962 ml) and 2N aqueous sodium hydroxide solution (24.9 ml), and the mixture was stirred with heating at 80° C. for 1 hr. After allowing to cool to room temperature, the crystals were collected by filtration and dried to give 6-amino-3-cyclopropyl-1-(2-fluoro-4-iodo-phenyl)-1H-pyrimidine-2,4-dione 75 (178 g, yield from 48, 88%) as pale-yellow crystals.
