反応手順

A solution of 2-(4-chloro-phenyl)-2-(4-iodo-phenyl)-oxirane (0.60 g, 1.68 mmol), ethanolamine (0.5 mL, 8.3 mmol) and triethylamine (0.5 mL, 3.6 mmol) in iso-propanol (5 mL) was maintained at 50° C. for 72 hours then concentrated in vacuo. The residue was taken up in ethyl acetate and washed with saturated potassium carbonate solution/water (1:9). The aqueous phase was extracted a second time with ethyl acetate, then the combined extracts were washed with brine, dried (MgSO4), filtered and concentrated to give the title compound (701 mg, quantitative); LCMS (PS-A2) Rt 2.29 min [M+H]+ 418, [M−H2O+H]+ 400.
