실험 절차

4-[2-(2,4-Dichloro-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-1H-pyridin-2-one (Example 119, 100 mg) was dissolved in THF (10 mL), and treated with t-BuOK (34 mg). After 5 minutes stirring, bromo-acetic acid methyl ester (0.03 mL) was added and the reaction mixture was stirred at 55° C. for 17 h. The reaction mixture was then cooled down to r.t., poured into water (50 mL) and extracted twice with ethyl acetate. The combined organic phases were washed with brine, dried over MgSO4 and concentrated in vacuo. The residue was purified by flash chromatography (10 g silica gel, ethyl acetate/heptane 30:70) to give the title compound as colorless waxy solid (49 mg). MS (m/e)=438.1 (MH+).
