実験手順

To a solution of (S)-1-(4-bromophenyl)ethanamine (40 g, 0.2 mol) in methylene chloride (600 mL) and satd aq NaHCO3 (600 mL) was added triphosgene (27 g, 0.025 mol) at 0° C. The mixture was stirred for 15 min. The organic phase was separated, dried and concentrated to give 1-bromo-4-(1-isocyanato-ethyl)-benzene (35 g, crude).
