Reaction Steps

In a microwave vial, to a 1,4-dioxane (3.0 ml) suspension of 1-[4-chloro-6-(methylamino)-1,3,5-triazin-2-yl]-N-{[2-(trifluoromethyl)phenyl]methyl}-4-piperidine carboxamide (Intermediate 7d, 75 mg, 0.17 mmol, 1.0 equiv) was added (2-methylphenyl)boronic acid (29 mg, 0.21 mmol, 1.2 equiv), Na2CO3 (37 mg, 0.35 mmol, 2.0 equiv) in 3:1 CH3CN:H2O, and lastly Pd(PPh3)4 (10 mg, 0.0088 mmol, 0.05 equiv). The reaction mixture was heated at 150° C. for 25 minutes. The resulting suspension was diluted with ethyl acetate (10 ml), washed with water (5 ml), dried with sodium sulfate, filtered and concentrated under reduced pressure. The residue was taken up in 2.0 ml DMSO and purified via reverse-phase HPLC purification to afford the title compound. MS (ES+): m/e 501.0 [M+H]+.
