Procedure

2-Amino4-methylpyridine (99.0 g, 91.5 mmol) in acetic anhydride (250 mL) was warmed to 70° C. for two h. The mixture was cooled to room temperature and diethyl ether (100 mL) added. The product crystallized as white needle crystals. Filtering and drying in vacuo afforded N-(4-methyl-pyridin-2-yl)-acetamide (130 g, 95%).
