To a suspension of 0.1 g (0.55 mmol) of 2-acetyl-6-(3-hydroxypropyl)-pyridine, 0.14 g of 4-(5-trifluoromethyl-1,2,4-oxadiazol-3-yl)-2,6-dimethylphenol, 0.175 g (1.2 eq) of triphenylphosphine in DMF under nitrogen at 0° C. was added dropwise a solution of 0.097 g (1.2 eq) of DEAD in DMF. The bright red solution was stirred at room temperature overnight, diluted with water, and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, concentrated in vacuo, and the residue was purifed by MPLC to afford 2-acetyl-6-[3-[4-(5-trifluoromethyl-1,2,4-oxadiazol-3-yl)-2,6-dimethylphenoxy]-propyl]-pyridine.
