Versuchsvorschrift
To a stirred solution of phosgene (20% in Toluene, 24 mL, 45.9 mmol) (Aldrich) in ethyl acetate (25 mL) at 0° C. was added aminophenol (0.5 g, 4.59 mmol) (Aldrich). The reaction mixture was stirred at 0° C. for 30 minutes and then heated at 80° C. for 3 hours. The mixture was cooling down to room temperature to give crude 4-isocyanato-phenol as 0.18 M solution in toluene and used for the next step without further purification.
