Reaction Steps

Sodium cyanate (1.7 g, 0.02 mol) was dissolved in water (17 ml) at room temperature to obtain a clear solution. This solution was then charged drop wise to the clear solution of 3-trifluoromethyl-4-chloro aniline (5 g, 0.025 mol) in acetic acid (25 ml) at 40° C.-45° C. within 1-2 hours. The reaction mass was then agitated for whole day cooling gradually to room temperature. The obtained solid was then filtered, washed with water and vacuum dried at 50° C. to afford (4.5 g) the desired product, i.e., 1-(4-chloro-3-(trifluoromethyl)phenyl)urea.
