Procedure

To 6-chloro-N-(3-fluorobenzyl)-4-(trifluoromethyl)pyridin-2-amine (70 mg, 0.230 mmol) was added 2-fluoropyridin-4-ylboronic acid (58.3 mg, 0.414 mmol), PdCl2(dppf).CH2Cl2 adduct (22.52 mg, 0.028 mmol), DME (1.2 ml), and 2M sodium carbonate (0.460 ml, 0.919 mmol). The resulting reaction mixture was stirred at 105° C. until completion as indicated by LCMS, about 6 hours. The reaction mixture was cooled, 15 ml of ethyl acetate and 5 ml of methanol was added, filtered and concentrated to yield a crude solid. The solid was purified by prep LC. The product was free-based using 200 ml of ethyl acetate and washed with saturated sodium bicarbonate (1×), water (2×), saturated salt solution (1×), dried sodium sulfate, filtered and concentrated to a constant mass, yielding 35 mg of titled compound as free base. LCMS (m/z): 366.2 (MH+), retention time=1.20 min.
