Procedure

A solution of methyl 2-(4-hydroxyphenyl)cyclopropanecarboxylate (0.152 g, 0.790 mmol), {4-[((3-methylbutyl){4-[4-(trifluoromethyl)phenyl]-1,3- thiazol-2-yl}amino)methyl]phenyl}methanol (0.312 g, 0.718 mmol) and tributylphosphine (0.291 g, 1.44 mmol) in toluene (15 mL) was stirred, 1,1′-(azodicarbonyl)dipiperidine (0.363 g, 1.44 mmol) was added, and the mixture was stirred at room temperature for 60 hr. Hexane (15 mL) was added to the reaction mixture, and the precipitated insoluble material was filtrated. The filtrate was concentrated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate:hexane=0:100-30:70) to give the title compound (0.202 g, yield 42%) as a colorless oil.
