Procedure
A solution of (3R)-3-(4-bromophenyl)piperidine obtained in Reference Example 15 (0.21 g, 0.9 mmol), 2-chloro-6-(3-fluoropyridin-4-yl)-3-methyl-3H-pyrimidine-4-one (0.21 g, 0.9 mmol), and triethylamine (0.30 g, 3.0 mmol) in tetrahydrofuran (10 ml) was stirred at 95° C. for 3 hours. The solvent was removed in vacuo and the residue was partitioned between water and dichloromethane. The organic layer was dried over anhydrous sodium sulfate and the solvent was removed under reduced pressure. The resulting residue was purified by silica gel column chromatography (chloroform/methanol=10/1) to afford 2-((3R)-3-(4-bromophenyl)piperidin-1-yl)-6-(3-fluoropyridin-4-yl)-3-methyl-3H-pyrimidine-4-one (0.24 g, 62%) as colorless crystals.
