Procedure

{8-[2-(2,2-Difluoro-ethoxy)-4-methanesulfonyl-phenyl]-[1,2,4]triazolo[1,5-a]pyridin-2-yl}-(2,3,4,5-tetrahydro-1H-3-benzazepin-7-yl)-amine was prepared from 7-{8-[2-(2,2-difluoro-ethoxy)-4-methanesulfonyl-phenyl]-[1,2,4]triazolo[1,5-a]pyridin-2-ylamino}-1,2,4,5-tetrahydro-3-benzazepine-3-carboxylic acid tert-butyl ester (0.285 g, 0.465 mmol) and trifluoroacetic acid (2 mL) in a manner analogous to Example 312 to give product (0.203 g, 85%). MP=128-131° C. 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 9.56 (s, 1H), 8.82 (d, 1H), 7.95 (d, 1H), 7.72 (s, 1H), 7.65 (m, 2H), 7.40 (d, 1H), 7.32 (s, 1H), 7.09 (t, 1H), 7.01 (d, 1H), 6.22 (br m, 1H), 4.53 (m, 2H), 2.84 (br m, 8H), 2.67 (br m 1H), 2.50 (s, 3H). MS=514 (MH)+.
