Triethylamine (0.156 mL, 1.12 mmol), tetrakistriphenylphosphine palladium (43.0 mg, 0.036 mmol) and copper (I) iodide (7.0 mg, 0.037 mmol) were added to a solution of (5-{4-[1-ethyl-1-(3-methyl-4-trifluoromethanesulfonyloxy-phenyl)-propyl]-phenyl}-pyridin-3-yl)-acetic acid methyl ester (Example 144-(2); 0.1 g, 0.186 mmol) and 1-ethynyl-cyclohexanol (69.6 mg, 0.56 mmol) in acetonitrile (0.9 mL), and the mixture was stirred with microwave heating at 160° C. for five minutes. The reaction solution was purified by silica gel chromatography (hexane:ethyl acetate=1:1) to give the title compound (63.6 mg, 66%).
