Reaction Steps

N-methoxycarbonyl-3-chloro-5-fluoroaniline (51.8 gms, 254M) is added to a mixture of hydrazine hydrate (125 ml) and isobutyl alcohol (160 ml). The mixture is heated to 100° for 10 hours under nitrogen. The solution is cooled to room temperature, diluted with water and filtered. The solid is rinsed with water (2×) and dried under vacuum to give 4-(3-chloro-5-fluorophenyl)semicarbazide as a white solid.
