Reaction Steps

[8-(4-Methanesulfonyl-piperazin-1-yl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-(4-methoxy-phenyl)-amine was prepared from (8-bromo-[1,2,4]triazolo[1,5-a]pyridin-2-yl)-(4-methoxy-phenyl)-amine (50.0 mg, 0.157 mmol) and 1-methanesulfonyl-piperazine (29.0 mg, 0.176 mmol) in a manner analogous to example 30. The title compound was isolated as an off-white solid (0.021 g, 33%). MP=240-241° C. 1H NMR (400 MHz, CDCl3, δ, ppm): 8.11 (dd, J=6.5, 1.1 Hz, 1H), 7.51-7.46 (m, 2H), 6.93-6.88 (m, 2H), 6.77 (dd, J=7.7, 6.6 Hz, 1H), 6.73 (s, 1H), 6.71 (dd, J=7.7, 1.0 Hz, 1H), 3.81 (s, 3H), 3.59-3.54 (m, 4H), 3.50-3.45 (m, 4H), 2.83 (s, 3H). MS=403 (MH)+.
