실험 절차

To a solution of 2-[4,6-dichloro-2-(morpholin-4-yl)pyrimidin-5-yl]ethanol (Preparation 1) (7.8 g, 28.0 mmol) and tert-butyl(3S)-3-amino-3-methylpyrrolidine-1-carboxylate (Preparation 4) (8.4 g, 42.1 mmol) in NMP (58 mL) was added DIPEA (18.1 g, 140 mmol) at 15° C. and the resulting mixture was stirred at 130° C. for 60 h. The mixture was diluted with EtOAc (100 mL) and washed with water (100 mL). The aqueous layer was extracted with EtOAc (100 mL×2). The combined organic layers were washed with brine (100 mL×5), dried over Na2SO4, filtered and concentrated to give 16 g of a brown gum. The crude product was purified by silica gel column chromatography eluting with a gradient of petroleum ether/EtOAc (20:1 to 8:1) to give the title compound (9.1 g, 73%) as a light yellow solid. m/z (APCI+) for C20H32N5O4Cl 442.0 [M+H]+.
