Procedure

4-{4-[8-(4-Cyano-phenyl)-[1,2,4]-triazolo[1,5-a]pyridin-2-ylamino]-phenyl}-piperidine-1-carboxylic acid tert-butyl ester was prepared from 2-chloro-8-(4-cyano-phenyl)-[1,2,4]-triazolo[1,5-a]pyridine (0.164 g, 0.644 mmol) and 4-(4-amino-phenyl)-piperidine-1-carboxylic acid tert-butyl ester (0.214 g, 0.773 mmol) in a manner analogous to Example 311a and 311b to give product (0.181 g, 57%). MP=96-100° C. 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 9.70 (s, 1H), 8.85 (d, 1H), 8.40 (d, 2H), 8.00 (m, 3H), 7.62 (d, 2H), 7.15 (m, 3H), 4.05 (m, 2H), 2.80 (br m, 2H), 2.60 (m, 1H), 1.75 (m, 2H), 1.45 (m, 2H), 1.41 (s, 9H). MS=495 (MH)+.
