Reaction Steps

Into a microwave vial was added 2-amino-5-(6-piperidin-1-ylpyridin-3-yl)thiophene-3-carbonitrile (225 mg, 0.79 mmol), 1-propanol (6.2 ml), and 25% sodium hydroxide (1.8 ml) and the mixture was heated in the microwave to 130° C. for 30 min. The reaction mixture was diluted with ethyl acetate and sodium bicarbonate to neutralize, extracted with ethyl acetate (3×100 mL), dried over magnesium sulfate, filtered and the solvent was evaporated under reduced pressure. The residue was purified by column chromatography on silica gel, eluting with ethyl acetate/methanol to afford the title compound as a solid.
