Procedure

A stirred solution of 2-methyl-2-(3-methyl-4-(4-(methylamino)-5-(trifluoromethyl)pyrimidin-2-ylamino)-1H-pyrazol-1-yl)propanamide (250 mg, 0.7 mmol) in POCl3 (5 mL) was stirred at 90° C. for 1 hour. POCl3 was removed by evaporation, the mixture was added into ice/H2O (10 ml) and the pH of the solution was adjusted to 8 with sat.Na2CO3, the aqueous phase was extracted with ethyl acetate (5 mL×3). The combined organic phase was washed with sat. sodium chloride (10 mL), dried over anhydrous sodium sulfate, filtered and concentrated to dry to give a residue which was purified by recrystallization to give 2-methyl-2-(3-methyl-4-(4-(methylamino)-5-(trifluoromethyl)pyrimidin-2-ylamino)-1H-pyrazol-1-yl)propanenitrile (100 mg, 42%) as a white solid. 1H-NMR (300 MHz, DMSO-d6) δ ppm 9.18 (s, 1H), 8.29 (s, 1H), 8.14 (s, 1H), 7.10 (s, 1H), 2.91 (d, 3H), 2.22 (s, 3H), 1.94 (s, 2H). LCMS (m/z) ES+340 (m+1). Purity, 99.3% (HPLC at 214 nm); Ki=0.0005.
