실험 절차

To a solution of 2-(3-methoxy-phenyl)-ethylamine (1) (50.0 g, 331 mmol) and concentrated HCl (27.6 mL) in water (350 mL), potassium cyanate (28.2 g, 348 mmol) was added and stirred at 50° C. for 2 hours, then at room temperature for 2 days. Formed precipitate was collected by filtration. The solid was washed with water and dried under reduced pressure to give the title compound (53.4 g, 83%). MS (ESI) (M+H)+ 195.
