Versuchsvorschrift
A mixture of benzyl 4-(3,3,3-trifluoro-2-hydroxypropoxy)piperidine-1-carboxylate (983 mg), mesyl chloride (0.438 mL), triethylamine (0.789 mL) and THF (10 mL) was stirred at 0° C. for 1 hr, and then at room temperature overnight. Water was added thereto, and the obtained mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (1.12 g).
