Product 1
Procedure
2-Chloro-8-(2-methoxy-5-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridine was prepared from 8-bromo-2-chloro-[1,2,4]triazolo[1,5-a]pyridine (0.500 g, 2.15 mmol) and 2-methoxy-5-trifluoromethylbenzeneboronic acid (0.710 g, 3.23 mmol) in a manner analogous to Example 311a to give product (0.636 g, 90%). MS=328 (MH)+. 315b) 7-[8-(2-Methoxy-5-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamino]-1,2,4,5-tetrahydro-3-benzazepine-3-carboxylic acid tert-butyl ester was prepared from 2-chloro-8-(2-methoxy-5-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridine (0.630 g, 1.92 mmol) and 7-amino-1,2,4,5-tetrahydro-3-benzazepine-3-carboxylic acid tert-butyl ester (0.605 g, 2.31 mmol) in a manner analogous to Example 311b to give product (0.750 g, 71%). 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 9.56 (s, 1H), 8.79 (d, 1H), 7.95 (s, 1H), 7.82 (d, 1H), 7.65 (d, 1H), 7.42 (m, 3H), 7.05 (m, 2H), 3.85 (s, 3H), 3.42 (m, 4H), 2.75 (m, 4H), 1.41 (s, 9H): MS=554 (MH)+.
