(2-Methoxy-phenyl)-[8-(4-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-amine was prepared from (8-bromo-[1,2,4]triazolo[1,5-a]pyridin-2-yl)-(2-methoxy-phenyl)-amine (50.0 mg, 0.157 mmol) and (4-trifluoromethylphenyl)boronic acid (33.0 mg, 0.174 mmol) with Pd(dppf)Cl2 (0.012 g) as the catalyst in a manner analogous to Step 2e. The reaction product was isolated as a white solid (0.032 g, 53%). MP=184-186° C. 1H NMR (400 MHz, CDCl3, δ, ppm): 8.49 (dd, J=6.8, 0.9 Hz, 1H), 8.38 (dd, J=8.0, 1.3 Hz, 1H), 8.14 (d, J=8.4 Hz, 2H), 7.78 (d, J=8.3 Hz, 2H), 7.63-7.58 (m, 2H), 7.08-6.88 (m, 4H), 3.92 (s, 3H). MS=385 (MH)+.
