실험 절차

To a solution of 1-[4-ethyl-2-(4-trifluoromethyl-phenyl)-oxazol-5-yl]-ethanol (0.114 g, 0.400 mmole) and 3-(4-Hydroxy-2-methyl-phenyl)-propionic acid methyl ester (0.0789, 0.400 mmole) in toluene (2 mL) at room temperature, is added tributylphosphine (0.200 mL, 0.800 mmole) followed by a solution of 1,1′-(azodicarbonyl)-dipiperidine (0.201 g, 0.800 mmole) in toluene (2 mL). The reaction is stirred overnight, then diluted with hexane (10 mL). The precipitate is removed through filtration and the filtrate is concentrated, loaded to a silica gel column, eluted with ethyl acetate in hexane (0–15%) and concentrated to provide the titled compound as a white solid. Mass [EI+] 462 (M+H)+.
