To a solution of methyl 3-(4-{[(2-nitrophenyl)sulfonyl]amino}phenyl)propanoate (182 mg, 0.5 mmol), (4-{[5-(4-fluorophenyl)-1-methyl-1H-pyrazol-4-yl]methoxy}phenyl)methanol (156 mg, 0.5 mmol) and triphenylphosphine (262 mg, 1.0 mmol) in dichloromethane (5 mL) was added diethyl azodicarboxylate (40% toluene solution, 435 mg, 1.0 mmol) at room temperature, and the mixture was stirred at room temperature for 1 hr. The reaction mixture was purified by silica gel column chromatography (10%-80% ethyl acetate/hexane) to give a yellow oil containing the title compound.
