Procedure
A solution of 2-chloro-6-(3-fluoropyridin-4-yl)-3-methyl-3H-pyrimidin-4-one (0.24 g, 1.0 mmol), (2RS)-2-benzyl-pyrrolidine (0.20 g, 1.2 mmol) and triethylamine (0.3 g, 3.0 mmol) in tetrahydrofuran (4 ml) was stirred for 5 hours at 40° C. The solution was partitioned between water and ethyl acetate, and the organic layer was washed with brine, dried over sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent; chloroform/ethyl acetate=3/2) to afford 2-((2RS)-2-benzyl-pyrrolidin-1-yl)-6-(3-fluoro-pyridin-4-yl)-3-methyl-3H-pyrimidin-4-one (0.29 g, 80%).
