실험 절차

To a solution of [5-(4-Trifluoromethyl-phenyl)-thiophen-2-yl]-methanol (0.063 g, 0.232 mmole) and 3-(4-Hydroxy-2-methyl-phenyl)-propionic acid methyl ester (0.045 g, 0.232 mmole) in toluene (2 mL) at room temperature, is added tributylphosphine (0.087 mL, 0.348 mmole) followed by a solution of 1,1′-(azodicarbonyl)-dipiperidine (0.088 g, 0.348 mmole) in toluene (2 mL). The reaction is stirred overnight, and 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 white solid.
