実験手順
A solution of methyltriphenylphosphonium bromide (101 mg; 0.28 mmol) in 0.76 ml of THF was treated under nitrogen with potassium tert-butoxide (0.28 ml of a 1M solution in tert-butanol). After 10 minutes, ethyl 2-[4-(2-{(5-acetylpyridin-2-yl)[4-(trifluoromethyl)benzyl]amino}ethyl)phenoxy]-2-methylpropanoate (100 mg; 0.19 mmol) was added. After 2 hours the reaction mixture was concentrated and the residue was partitioned between ethyl acetate and water. The organic phase was dried over sodium sulfate and concentrated. Purification by flash chromatography using 10% ethyl acetate-hexane mixtures afforded ethyl 2-[4-(2-{(5-isopropenylpyridin-2-yl)[4-(trifluoromethyl)benzyl]amino}ethyl)phenoxy]-2-methylpropanoate (30 mg; 30% yield).
