Procedure
4-[1-(3-Bromo-phenyl)-piperidin-4-yl]-morpholine was prepared from 4-piperidin-4-yl-morpholine (0.21 g, 1.2 mmol) and 3-bromophenylboronic acid (0.50 g, 2.5 mmol) in a manner analogous to Step 49a. The reaction product was isolated as a tan resin (0.238 g, 59%). 1H NMR (400 MHz, CDCl3, δ, ppm): 7.08 (t, J=7.1 Hz, 1H), 7.03 (s, 1H), 6.92 (d, J=7.3 Hz, 1H), 6.83 (d, J=8.6 Hz, 1H), 3.75-3.68 (m, 6H), 2.79-2.70 (m, 2H), 2.60-2.55 (m, 4H), 2.37-2.28 (m, 1H), 1.97-1.89 (m, 2H), 1.68-1.56 (m, 2H). MS=325, 327 (MH)+. 57b) [8-(4-Methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-[3-(4-morpholin-4-yl-piperidin-1-yl)-phenyl]-amine was prepared from 8-(4-methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (75.0 mg, 0.260 mmol) and 4-[1-(3-bromo-phenyl)-piperidin-4-yl]-morpholine (100.0 mg, 0.3075 mmol) with 2,2′-bis-dicyclohexylphosphanyl-biphenyl (30.0 mg, 0.0549 mmol) as the ligand in a manner analogous to Step 2d. The title compound was isolated as a yellow solid (0.035 g, 25%). MP=230-236° C. 1H NMR (400 MHz, CDCl3, δ, ppm): 8.49 (d, J=6.4 Hz, 1H), 8.26 (d, J=8.0 Hz, 2H), 8.08 (d, J=7.1 Hz, 2H), 7.66 (d, J=8.0 Hz, 2H), 7.35 (s, 1H), 7.24-7.18 (m, 1H), 7.01 (d, J=6.7 Hz, 1H), 6.96 (d, J=7.9 Hz, 1H), 6.84 (s, 1H), 6.60 (d, J=8.4 Hz, 1H), 3.81 (d, J=11.7 Hz, 2H), 3.77-3.72 (m, 4H), 3.10 (s, 3H), 2.78 (t, J=11.8 Hz, 2H), 2.63-2.58 (m, 4H), 2.40-2.30 (m, 1H), 1.97 (d, J=12.7 Hz, 2H), 1.74-1.62 (m, 2H). MS=533 (MH)+.
