To a solution of 0.95 g (2.41 mmol) of 5-[3-[4-(5-trifluoromethyl-1,2,4-oxadiazol-3-yl)-2,6-dimethylphenoxy]-propyl]-2 (1H)-pyridone, 20 drops of TDA-1, and 0.5 ml of methyl iodide in 50 ml of dry DMF was added 0.96 g (3 eq) of milled K2CO3. The mixture was filtered and concentrated in vacuo to afford 0.9 g (91.8%) of 3-[3-[4-(5-trifluoromethyl-1,2,4-oxadiazol-3-yl)-2,6-dimethylphenoxy]-propyl]-1-methyl-2-pyridone, as a white solid, which was recrystallized from isopropyl acetate to yield a white solid, 143°-146° C.
