Versuchsvorschrift

1-Chloro-2-isocyanato-ethane (0.81 mL, 9.42 mmol) was added dropwise to a stirred solution of naphthalen-2-ylamine (900 mg, 6.28 mmol) in toluene (50 mL) over a period of 30 minutes at 0° C. The reaction temperature was maintained at room temperature for 5 hours. The reaction was monitored by TLC (5% MeOH in chloroform). The reaction mixture was filtered, washed with toluene and dried under reduced pressure to afford 1.3 g (83% yield) of 1-(2-chloro-ethyl)-3-naphthalen-2-yl-urea.
