To a sealable tube containing 5-ethynylpyrimidin-2-amine (172 mg, 1.44 mmol), PdCl2(PPh3)2 (25 mg, 0.036 mmol), 3-iodo-4-methyl-N-(3-(trifluoromethyl)phenyl)benzamide (292 mg, 0.72 mmol) was added MeCN (10 mL) and Et3N (3 mL) followed by CuI (6.8 mg, 0.036 mmol). The tube was sealed and heated at 90° C. for 1 h. The reaction was allowed to cool to room temperature and concentrated under reduced pressure. The resulting brown solid was reconstituted in MeOH:CH2Cl2 (1:1, 10 mL) and silica gel was added and reconcentrated. The silica-gel combined crude mixture was purified via automated flash chromatography (silica gel, 0 to 5% MeOH in CH2Cl2, gradient elution) to afford 3-(2-(2-aminopyrimidin-5-yl)ethynyl)-4-methyl-N-(3-(trifluoromethyl)phenyl)benzamide. MS m/z=397 [M+H]+. Calc'd for C21H15F3N4O: 396
