実験手順

Pyridine sulfur trioxide complex (37.7 g, 237 mmol) was added portionwise over 20 minutes to a stirred cold (0° C.) solution of N-[(1S)-1-(3-fluorophenyl)-3-hydroxypropyl]acetamide (25 g, 118 mmol), DMSO (16.5 ml, 233 mmol) and triethylamine (33 ml, 237 mmol) in dichloromethane (240 ml). After two hours stirring at room temperature, solvent was evaporated under reduced pressure and the residue applied directly to a silica gel column. Eluting with a gradient system starting with ethyl acetate:dichloromethane (50:50 by volume) then ethyl acetate:dichloromethane (80:20 by volume) and finally ethyl acetate gave the title compound as a colourless oil which solidified on standing (13.9 g).
