Reaction Steps

7-[5-(2-Methoxy-5-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl-amino]-1,2,4,5-tetrahydro-3-benzazepine-3-carboxylic acid tert-butyl ester was prepared from 2-chloro-5-(2-Methoxy-5-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridine (0.46 g, 1.4 mmol) and 7-amino-1,2,4,5-tetrahydro-3-benzazepine-3-carboxylic acid tert-butyl ester (0.557 g, 2.12 mmol) in a manner analogous to Example 2d. Product was isolated as a foam (0.33 g, 42%). 1H NMR (400 MHz, CDCl3, δ, ppm): 7.94 (brs, 1H), 7.80-7.77 (m, 1H), 7.55-7.49 (m, 2H), 7.20-7.15 (m, 1H), 7.05-7.00 (m, 1H), 7.00-6.96 (m, 1H), 6.90 (brs, 1H), 3.88 (s, 3H), 3.60-3.48 (m, 4H), 2.89-2.78 (m, 4H), 1.52 (s, 9H). MS=554 (MH)+.
