Reaction Steps

To a solution of 2-(4-amino-3-methyl-1H-pyrazol-1-yl)-2-methylpropanamide (250 mg, 1.37 mmol) in 2-methoxyethanol (5 mL) was added 2-chloro-N-methyl-5-(trifluoromethyl)pyrimidin-4-amine (290 mg, 1.37 mmol) and trifluoroaceticacid (156 mg, 1.37 mmol), the reaction was stirred at 70° C. for about 0.5 h. The reaction mixture was cooled to ambient temperature followed with the addition of water (10 mL) and the pH of solution was adjusted to 8 with sat. Na2CO3 The aqueous phase was extracted with ethyl acetate (10 mL×3), the combined organic phase was dried over anhydrous sodium sulfate, filtered and concentrated to dry to give a residue which was purified by column chromatography on silica gel (CH2Cl2:MeOH=20:1) to give 2-methyl-2-(3-methyl-4-(4-(methylamino)-5-(trifluoromethyl)pyrimidin-2-ylamino)-1H-pyrazol-1-yl)propanamide (250 mg, 51%) as white solid. LCMS (m/z) ES+358 (m+H).
