실험 절차

0.6 g (0.0015 mol) of N-(1-hydroxy-2,2,2-trifluoroethyl)-4-methoxy-6-{3-(trifluoromethyl)phenoxy}-2-pyridine carboxamide was dissolved in a mixed solvent of dichloromethane and DMF. The obtained solution was mixed with 0.064 g (ca. 60% in mineral oil; 0.0015×1.1 mol) of NaH and then with 0.42 g (0.0015×2.0 mol) of methyl iodide, followed by treating the solution under reflux for about 8 hours. The reaction solution was distributed in hexane-saturated sodium bicarbonate water and washed with saturated brine. The organic phase of the solution was dried with anhydrous sodium sulfate, concentrated and purified by silica gel column chromatography (eluting solution: ethyl acetate/hexane), thereby obtaining an aimed product.
