Reaction Steps

To a reactor was charged 2-chloro-4-{[(1R,3R,4R)-3-hydroxy-4-methylcyclohexyl]amino}pyrimidine-5-carboxamide (41 kg), t-butylamine (105.3 kg) and DMSO (205 L). The batch was heated to 68° C. under 10 psig of nitrogen pressure, held for 80 h, and cooled to 25° C. The batch was filtered through a 0.45 μm in-line filter to a second reactor. The batch was heated to 60° C., and water (205 L) was charged through a 0.45 μm in-line filter. The batch was seeded with micronized Compound 1 (820 g) agitated at 60° C. for over an hour, and water (615 L) was charged to the batch through a 0.45 μm in-line filter in 3 h at 60° C. The batch was agitated for 1 h at 60° C., cooled to 25° C. over 6 h, filtered, and washed with water (410 mL), which was filtered through a 0.45 μm in-line filter. The solids were dried in a vacuum oven at 40° C. with nitrogen bleed for over 72 h to give 2-(tert-butylamino)-4-{[(1R,3R,4R)-3-hydroxy-4-methylcyclohexyl]amino}pyrimidine-5-carboxamide as Form A and a white solid (43.5 kg, 94% yield). 1H NMR (DMSO-d6) δ 0.95 (d, J=6.2 Hz, 3H), 0.97-1.28 (m, 4H), 1.37 (s, 9H), 1.60-1.75 (m, 1H), 1.83-2.00 (m, IH), 2.06-2.26 (m, 1H), 2.86-3.07 (m, 1H), 3.74-4.01 (m, 1H), 4.59 (d, J=5.7 Hz, 1H), 6.65 (br. s., 1H), 7.03 (br. s., 1H), 7.57 (br. s., 1H), 8.36 (s, 1H), 8.93 (br. s., 1H).
