Reaction Steps

8-(3,4-Difluorophenyl)-N-((3S,4R)-3-methoxypiperidin-4-yl)-[1,2,4]triazolo[1,5-a]pyridin-2-amine dihydrochloride (28 mg, 64.8 μmol) was extracted with dichloromethane/2 M NaOH. The organic layers were washed with brine, dried over sodium sulfate and evaporated. The residue was dissolved in dioxane (0.5 mL) and to this solution 4-chloro-6-methylpyrimidine (9.2 mg, 71.2 μmol) and DIPEA (17.0 μL, 97.2 μmol) were added. Argon was bubbled through the solution for 5 minutes, and then heated in the microwave at 130° C. for 2×30 minutes. After evaporation, purification by chromatography (silica gel, 10 g, 0 to 10% methanol in dichloromethane) afforded the title compound (18 mg, 62%) as an off white foam.
