To a 100 mL RBF, was added (R)-isopropyl-pyrrolidin-2-ylmethyl-amine (0.13 g, 0.6 mmol), and 50 mL dichloromethane at 0° C. under nitrogen. 0.28 mL diisopropylethylamine (1.6 mmol) was added drop wise, and stirred for 10 min. 2-Chloro-3-methyl-6-pyridin-4-yl-5-m-tolyl-3H-pyrimidin-4-one (0.16 g, 0.5 mmol) was added in one portion, and stirred at 0° C. to rt for 12 h. (This meta-methyl chloro-intermediate was synthesized by a similar procedure as that of 5-(3-Bromo-phenyl)-2-chloro-3-methyl-6-pyridin-4-yl-3H-pyrimidin-4-one.) The mixture was diluted with 100 mL dichloromethane, washed with sat. NaHCO3 and brine. After purified by flash chromatography, the title compound was obtained in 0.219 g as pale yellow solid. MS (ES+): 418 (M+H)+.
