Procedure

2-Cyano-6-n-propylpyridine (10 g) was dissolved in a solution of sodium methoxide in methanol prepared from methanol (100 ml) and metallic sodium (0.32 g). After standing overnight, acetic acid (0.82 g) was added thereto, followed by concentration under reduced pressure. The resulting residue was dissolved in ether (200 ml) and insoluble materials were filtered out. The filtrate was concentrated under reduced pressure to obtain methyl 2-picolineimidate (11.5 g, yield: 94 %).
