実験手順
112 g (1.13 mol) phosgene are piped into 500 mL THF. Then a solution of 52 g (0.34 mol) 2-(2-amino-phenyl)-propan-2-ol, prepared from 2-aminoacetophenone and methylmagnesium iodide, in 300 mL THF is added. The reaction mixture is left to stand overnight, evaporated down and combined with 500 ml pyridine. After the pyridine has been distilled off water is added and the mixture is extracted with diethyl ether. The organic phases are washed successively with 2 N hydrochloric acid, sodium hydroxide solution and water, dried with sodium sulphate and evaporated down. The residue remaining (46 g) is further reacted directly without any more purification.
