Procedure

3-[(2-Chloro-[1,2,4]triazolo[1,5-a]pyridin-8-ylamino)-methyl]-pyrrolidine-1-carboxylic acid tert-butyl ester was prepared from 8-bromo-2-chloro-[1,2,4]triazolo[1,5-a]pyridine (500.0 mg, 2.151 mmol) and 3-aminomethyl-pyrrolidine-1-carboxylic acid tert-butyl ester (475.0 mg, 2.372 mmol) in a manner analogous to Example 2d. Product isolated as pale yellow viscous oil (0.544 g, 72%). 1H NMR (400 MHz, CDCl3, δ, ppm): 7.88 (d, J=6.6 Hz, 1H), 6.89 (t, J=7.3 Hz, 1H), 6.72 (d, J=7.9 Hz, 1H), 4.98 (br s, 1H), 3.65-3.08 (m, 6H), 2.64-2.51 (m, 1H), 2.15-2.05 (m, 1H), 1.80-1.65 (m, 1H), 1.47 (s, 9H). 163 b) 3-({2-[4-(4-Methyl-piperazin-1-yl)-phenylamino]-[1,2,4]triazolo[1,5-a]pyridin-8-ylamino}-methyl)-pyrrolidine-1-carboxylic acid tert-butyl ester was prepared from 3-[(2-chloro-[1,2,4]triazolo[1,5-a]pyridin-8-ylamino)-methyl]-pyrrolidine-1-carboxylic acid tert-butyl ester (500.0 mg, 1.421 mmol) and 4-(4-methyl-piperazin-1-yl)-phenylamine (300.0 mg, 1.568 mmol) with 2,2′-bis-dicyclohexylphosphanyl-biphenyl (78.0 mg, 0.143 mmol) as the ligand in a manner analogous to Example 2d. Product isolated as a tan foam (0.284 g, 39%). 1H NMR (400 MHz, CDCl3, δ, ppm): 7.81 (d, J=6.5 Hz, 1H), 7.46 (d, J=8.9 Hz, 2H), 6.96 (d, J=8.9 Hz, 2H), 6.71 (t, J=7.3 Hz, 1H), 6.59 (s, 1H), 6.35 (d, J=7.7 Hz, 1H), 4.75 (br s, 1H), 3.66-3.05 (m, 10H), 2.63-2.52 (m, 5H), 2.36 (s, 3H), 2.15-2.04 (m, 1H), 1.80-1.65 (m, 1H), 1.46 (s, 9H). MS=507 (MH)+.
