2-Chloro-8-(2-methoxymethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridine was prepared from 8-bromo-2-chloro[1,2,4]triazolo[1,5-a]pyridine (0.71 g, 3.0 mmol) and 2-methoxymethyl)phenylboronic acid (0.71 g, 4.3 mmol) in a manner analogous to Example 2c. Product was isolated as a foam (0.82 g, 98%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.55 (d, J=6.3 Hz, 1H), 7.64-7.57 (m, 2H), 7.50-7.43 (m, 1H), 7.25-7.21 (m, 2H), 7.17 (t, J=7.3 Hz, 1H), 4.37 (s, 2H), 3.27 (s, 3H), MS=328 (MH)+. 241b) 7-[8-(2-Methoxymethyl-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-8-(2-Methoxymethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridine (0.40 g, 1.46 mmol) and 7-amino-1,2,4,5-tetrahydro-3-benzazepine-3-carboxylic acid tert-butyl ester (0.46 g, 1.75 mmol) in a manner analogous to Example 2d. Product was isolated as a foam (0.5 g, 70%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.48 (d, J=6 Hz, 1H), 7.61 (d, J=6 Hz, 1H), 7.51-7.42 (m, 4H), 7.00-6.89 (m, 3H), 6.79 (s, 1H), 3.62-3.45 (m, 4H), 3.29 (s, 3H), 2.84-2.74 (m, 4H), 1.52 (s, 9H). MS=500 (MH)+.
