Procedure

1-Chloro-2-isocyanato-ethane (2.36 g, 0.02239 mmol) was added dropwise to a stirred solution of m-tolylamine (2 g, 0.01866 mmol) in toluene (50 mL) over a period of 30 minutes at 0° C. The reaction mixture was stirred at room temperature for 12 hours. The reaction was monitored by TLC (5% MeOH in DCM). The reaction mixture was filtered, washed with toluene and dried under reduced pressure to afford 3.8 g (97% yield) of 1-(2-chloro-ethyl)-3-m-tolyl-urea.
