実験手順

A solution of 4-[1-(4-pentylphenylethyl)-5-methyl-1H-pyrrol-2-yl]phenol (1.82 g, 5.2 mmol), ethyl (S)-2-hydroxy-3-phenylpropanoate (1.0 g, 5.1 mmol), 1,1′-(azodicarbonyl)dipiperidine (1.29 g, 5.1 mmol) and triphenylphosphine (1.34 g, 5.1 mmol) in toluene (5 ml) was stirred at 80° C. for 12 hours. The reaction solution was poured into water and extracted with ethyl acetate. The extract was washed with saturated brine and dried over magnesium sulfate anhydride. The solvent was removed under reduced pressure and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=20:1) to give the object compound as an oily substance. 660 mg, (yield 23%)
