Procedure

A suspension of 4-[8-(4-methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamino]-phenol (50.0 mg, 0.131 mmol), 4-(2-chloroethyl)-morpholine hydrochloride (27.0 mg, 0.145 mmol) and potassium carbonate (36.0 mg, 0.260 mmol) in acetonitrile (1 mL) was heated at 70° C. for 18 hours. The mixture was cooled to room temperature, diluted with acetonitrile (10 mL), filtered through a plug of diatomaceous earth and evaporated to an orange resin. The residue was purified via chromatography utilizing an ISCO automated purification apparatus with silica gel column (12 g) and 0%→10% methanol:dichloromethane solvent gradient. The title compound, [8-(4-Methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-[4-(2-morpholin-4-yl-ethoxy)-phenyl]-amine, was isolated as a yellow foam (0.047 g, 72%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.47 (d, J=6.5 Hz, 1H), 8.23 (d, J=8.4 Hz, 2H), 8.07 (d, J=8.3 Hz, 2H), 7.64 (d, J=7.4 Hz, 1H), 7.51-7.46 (m, 2H), 7.00 (t, J=7.0 Hz, 1H), 6.96-6.90 (m, 2H), 6.73 (s, 1H), 4.12 (t, J=5.8 Hz, 2H), 3.77-3.72 (m, 4H), 3.10 (s, 3H), 2.80 (t, J=5.6 Hz, 2H), 2.62-2.55 (m, 4H). MS=494 (MH)+.
