Procedure

5-Amino-N-(2-aminopyrimidin-5-yl)-2-methylbenzamide 9 (86 mg, 0.353 mmol) was taken up in CH2Cl2 (3 mL) and 3-(trifluoromethyl)benzoyl chloride (0.052 mL, 0.353 mmol) was added. The mixture was allowed to stir at rt for 2 h, becoming a thick yellow suspension. NEt3 (0.064 mL, 0.459 mmol) was added. After 0.5 h, a thick yellow suspension remained. Complete consumption of the amine starting material was indicated by LCMS. The crude reaction mixture was concentrated and the title compound was purified using automated medium pressure chromatography (Isco—40 g column; eluting with a linear gradient from 100% CH2Cl2 (A line) to 100% 90/10/1 CH2Cl2/MeOH/NH3 (B line) on silica gel) to afford N-(2-amino-5-pyrimidinyl)-2-methyl-5-(((3-(trifluoromethyl)phenyl)carbonyl)amino)benzamide 10 as an off-white solid. MS: m/z found 416 [MH+] (by ESI, positive ion); MS calculated for C20H16F3N5O2=415.13.
