실험 절차

Methanesulfonyl chloride (50 μl, 0.63 mmol) was added to a mixture of [(2R,3R,4R)-2-[(1R)-1-(3,5-bis(trifluoromethyl)phenyl)ethoxy]-3-(3,4-difluorophenyl)-tetrahydropyran-4-yl]methanol (Description 15; 235 mg, 0.49 mmol), triethylamine (133 ml, 0.97 mmol), 4-N,N-dimethylaminopyridine (3 mg, 0.02 mmol) and dichloromethane (5 ml) at 0° C. The mixture was stirred for 30 minutes, then quenched with saturated aqueous NaHCO3 and extracted into dichloromethane. The combined organic extracts were dried and concentrated. The product was used in the next step without further purification.
