Reaction Steps
To a solution of N-(1-(2-chloropyridin-4-yl)piperidin-4-yl)-8-(3,4-difluorophenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-amine (example 169c) (88 mg, 0.20 mmol) in EtOH (1 mL) was added sodium ethoxide solution (21% in ethanol, 75 L, 0.2 mmol) and the reaction mixture was heated in the microwave to 150° C. for 30 minutes. Again sodium ethoxide solution (21% in ethanol, 75 L, 0.2 mmol) was added and the resulting mixture heated to 150° C. for another 30 minutes. The mixture was then evaporated. Purification by chromatography (silica gel, 20 g, 0 to 100% methanol in dichloromethane) afforded the title compound (3 mg, 3%) as a colourless gum.
