262 a) 2-(2-Amino-[1,2,4]triazolo[1,5-a]pyridin-8-yloxymethyl)-benzonitrile was prepared from 2-amino-[1,2,4]triazolo[1,5-a]pyridin-8-ol (0.200 g, 1.33 mmol) 2-bromomethyl-benzonitrile (0.274 mL, 1.40 mmol) in a manner analogous to Example 260c. Product was isolated as a white solid. 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 8.21 (d, J=6.6 Hz, 1H), 7.94 (d, J=7.8 Hz, 1H), 7.78-7.76 (m, 2H), 7.62-7.58 (m, 1H), 7.07 (d, J=8.0 Hz, 1H), 6.81-6.78 (m, 1H), 5.94 (s, 2H), 5.44 (s, 2H). MS=266 (MH)+. 262 b) 2-{2-[4-(4-Methyl-piperazin-1-yl)-phenylamino]-[1,2,4]triazolo[1,5-a]pyridin-8-yloxymethyl}benzonitrile was prepared from 2-(2-amino-[1,2,4]triazolo[1,5-a]pyridin-8-yloxymethyl)-benzonitrile (115.0 mg, 0.434 mmol) and 1-(4-bromo-phenyl)-4-methyl-piperazine (128 mg, 0.500 mmol) in a manner analogous to Example 2d. Product was isolated as a pale orange solid (0.101 g, 53%). MP=156-157° C. 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 9.32 (s, 1H), 8.40 (d, J=6.5 Hz, 1H), 7.93 (d, J=7.8 Hz, 1H), 7.80 (d, J=4.5 Hz, 2H), 7.62-7.60 (m, 1H), 7.50 (d, J=8.9 Hz, 1H), 7.17 (d, J=8.5 Hz, 1H), 6.98-6.88 (m, 3H), 5.49 (s, 2H), 3.04-3.02 (m, 4H), 2.47-2.44 (m, 4H), 2.22 (s, 3H). MS=440 (MH)+.
