Reaction Steps
A solution of 4,5-dichloropyrimidine (0.6 g, 4.02 mmol), 3-amino-Boc-pyrrolidine (0.5 g, 2.6 mmol) and DIPEA (1.73 g, 13.3 mmol) in n-butanol (5.0 mL) was heated in a pressure tube (120° C., 12 h). It was cooled, quenched with water (10 mL) and was extracted with EtOAc (2×25 mL). The combined EtOAc extract was washed with water (5 mL), brine (5 mL), dried over Na2SO4 and concentrated under reduced pressure to afford tert-butyl 3-(6-chloropyrimidin-4-ylamino)pyrrolidine-1-carboxylate (0.4 g, 50%) as a yellow solid.
