Reaction Steps

A mixture of 2,4-dichloro-pyrimidine-5-carboxamide (10.0 g), DIPEA (11 mL) in NMP (30 mL) were stirred at 25° C. tert-Butylamine (6.6 mL) was charged to the mixture, and the mixture was stirred at 25° C. for 16 h. Water (100 mL) was added to the mixture at 25° C. The mixture was stirred for 1 h. The suspension was filtered, washed with water (50 mL) and dried in a vacuum oven at 40° C. with a nitrogen bleed for 24 h to give 4-(tert-butylamino)-2-chloropyrimidine-5-carboxamide as a white solid (8.7 g, 84%). 1H NMR (DMSO-d6) δ 9.41 (s, 1H), 8.55 (s, 1H), 8.19 (s, 1H), 7.67 (s, 1H), 1.42 (s, 9H).
