実験手順

Degassed N,N-dimethylformamide (0.37 mL) was added to 2-(4-{1-ethyl-1-[3-methyl-4-(4,4,4-trifluoro-3-methoxymethoxy-3-trifluoromethyl-butyl)-phenyl]-propyl}-2-methyl-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (Example 108-(1); 38.4 mg, 0.0623 mmol), (5-bromo-pyridin-3-yl)acetic acid methyl ester (Example 24-(2); 19.9 mg, 0.0865 mmol), tetrakis(triphenylphosphine)palladium (0) (9.0 mg, 0.0078 mmol) and potassium phosphate (28.2 mg, 0.133 mmol). After replacement with nitrogen, the mixture was heated while stirring at an external temperature of 85 to 95° C. for three hours. Water was added to the reaction mixture, followed by extraction with diethyl ether. The extract was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel chromatography (hexane/ethyl acetate=2/1) to give the title compound (32 mg, 80%).
