Diisopropylethylamine → 5-(3-Bromo-phenyl)-2-[2-(isopropylamino-methyl)-pyrrolidin-1-yl]-3-methyl-6-pyridin-4-yl-3H-pyrimidin-4-one

Participants

Reaction Steps

To a 100 mL RBF, was added (R)-isopropyl-pyrrolidin-2-ylmethyl-amine (0.78 g, 3.6 mmol), and 50 mL dichloromethane at 0° C. under nitrogen. 2.1 mL diisopropylethylamine (12 mmol) was added drop wise, and stirred for 10 min. 5-(3-Bromo-phenyl)-2-chloro-3-methyl-6-pyridin-4-yl-3H-pyrimidin-4-one (1.13 g, 3 mmol) was added in one portion. The mixture was stirred at 0° C. to rt for 12 h. The mixture was diluted with 100 mL dichloromethane, washed with sat. NaHCO3 and brine. After purified by flash chromatography, the title compound was yielded in 1.3 g as pale yellow solid. MS (ES+): 482 (M+H)+.
