Procedure

1,2-dimethoxyethane (3.0 ml) and aqueous 2 N sodium carbonate solution (1.0 ml) were added to 2-(1-cyclopentylpiperidin-4-yloxy)-5-bromopyrimidine (176 mg, 0.54 mmol), and then 4-(pyrrolidin-1-ylcarbonyl)phenylboronic acid (142 mg, 0.065 mmol) and tetrakis(triphenylphosphine)palladium(0) (30 mg, 0.026 mmol) were added thereto and stirred in a nitrogen atmosphere at 80° C. for 20 hours. The reaction mixture was cooled to room temperature, and water was added to it and extracted with ethyl acetate. The organic layer was washed with saturated saline solution, dried with anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified through silica gel column chromatography (C-200, chloroform:methanol=10:1) to obtain the entitled compound (130 mg, 57%).
