Procedure

Degassed N,N-dimethylformamide (0.32 mL) was added to 2-[4-(1-{4-[(E)-3-(t-butyl-dimethyl-silanyloxy)-4,4,4-trifluoro-3-trifluoromethyl-1-butenyl]-3-methyl-phenyl}-1-ethyl-propyl)-2-methyl-phenyl]-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (Example 77-(1); 35.8 mg, 0.0523 mmol), 2-bromopyrimidine-5-acetic acid ethyl ester (Example 43-(3); 37.3 mg, 0.152 mmol), tetrakis(triphenylphosphine)palladium (0) (29.8 mg, 0.0258 mmol) and potassium phosphate (48.7 mg, 0.229 mmol). After replacement with nitrogen, the mixture was heated while stirring at an external temperature of 91 to 100° C. for 10 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=4/1) to give the title compound (13 mg, 41%).
