Procedure
[8-(4-Methanesulfonyl-phenyl)-6-trifluoromethyl-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-[3-(4-methyl-piperazin-1-yl)-phenyl]-amine was prepared from 8-(4-methanesulfonyl-phenyl)-6-trifluoromethyl-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine and 1-(3-bromo-phenyl)-4-methyl-piperazine in a manner analogous to Step 2d and was isolated as a yellow solid (2% yield). 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 8.84 (s, 1H), 8.28 (d, J=8.3 Hz, 2H), 8.14 (d, J=7.2 Hz, 2H), 7.81 (s, 1H), 6.95 (m, 2H), 6.64 (d, 1H), 3.32 (bm, 4H), 3.14 (s, 3H), 2.67 (bm, 4H), 2.44 (s, 3H). MS=531.1 (MH)+.
