To a degassed solution of 6-bromo-7-(4-chlorophenyl)-3-((6-(trifluoromethyl)pyridin-3-yl)methyl)-[1,2,4]triazolo[4,3-a]pyridine (9.5 mg, 0.02 mmol), 2,4-dichlorophenylboronic acid (8.0 mg, 0.041 mmol) and K2CO3 (8.5 mg, 0.061 mmol) in 1,4-dioxane (0.3 mL) and H2O (0.1 mL) was added Pd(PPh3)4 (2.3 mg, 0.002 mmol) under argon at 20° C. The reaction mixture was heated at 100° C. for 2 h under argon, then allowed to cool to 20° C. The reaction was concentrated in vacuo, and the residue was purified using reverse phase preparative HPLC (Conditions: Phemomenex Luna 5μC18 30×75 mm; Eluted with 0% to 100% B, 10 min gradient, 100% B hold for 2 min, (A=90% H2O, 10% CH3CN, 0.1% trifluoroacetic acid and B=10% H2O, 90% CH3CN, 0.1% trifluoroacetic acid); Flow rate at 40 mL/min, UV detection at 220 nm) to afford 5.5 mg (55%) of the title compound as a white solid. LC/MS (method B): retention time=2.03 min, [M+H]+=533.2.
