Procedure

An slurry of 6-(3-cyclopropyl-3-fluoroazetidin-1-yl)-N-(3-methyl-1H-pyrazol-5-yl)-2-(methylsulfonyl)pyrimidin-4-amine (61 g, 170 mmol) and 3,3,3-trifluoro-N-(4-mercaptophenyl)propanamide (41 g, 175 mmol) in CH3CN (1300 mL) was heated to reflux for 1.5 hours. During this time, the slurry transforms from thin and yellowish to thick and brilliant white. The mixture was then cooled to 0° C. and stirred at this temperature for 15 min. Filtered and washed with cold CH3CN (650 mL). The resulting solid was dried for 20 hours at 38° C. under house vacuum. The white solid was charged to a suitable reactor with EtOAc (1300 mL) and NaHCO3 (sat) (1300 mL). The mixture was stirred until no more solid remained. Then, the layers were separated and washed the aqueous with EtOAc (390 mL). The combined organic layers were dried over MgSO4, filtered, washed with EtOAc (130 mL) and concentrated to minimal volume on rotavap. The resulting mixture was re-crystallized out of EtOAc and hexane to give the desired product as a white solid (56.2 g, 72%) 1H NMR (MeOD, 400 MHz): 0.40-0.45 (2H, m), 0.60-0.65 (2H, m), 1.3-1.4 (1H, m), 2.05 (2H, s), 3.25-3.40 (2H, m), 3.85-3.40 (4H, m), 5.40-5.50 (2H, m), 7.50-7.55 (2H, d), 7.65-7.70 (2H, d). ES+ 522.
