실험 절차

A 10% solution of aqueous NaOH (40 mL) was added to a solution of N-(6-methoxy-5-methylpyridin-2-yl)acetamide (2.21 g, 12.3 mmol) in MeOH (160 mL) and the reaction mixture was heated at 90° C. for 3 d. After cooling to rt and concentration in vacuo to remove the MeOH the aqueous residue was combined with that from a previous batch derived from N-(6-methoxy-5-methylpyridin-2-yl)acetamide (2.21 g, 12.3 mmol). The aqueous phase was diluted with H2O (40 mL) and extracted with DCM (3×150 mL). The combined organic phases were washed with brine, dried (Na2SO4) and combined with a previous batch of crude 6-methoxy-5-methylpyridin-2-amine (266 mg). Concentration in vacuo yielded the title compound (3.30 g, 23.9 mmol).
