실험 절차

In metal sealed tube were added 2-chloro-3-hyroxy-6-methylpyridine (1-014-02) (22.91 g) and 28% sodium methoxide/methanol solution (120 mL) and the reaction mixture was reacted at 150° C. for 3 days. To the reaction mixture was added ice and water (100 mL) and the reaction mixture was neutralized with acetic acid, and evaporated completely. The residue was purified by silica gel column chromatography (chloroform) to give the desired 2-methoxy-3-hyroxy-6-methylpyridine (1-014-03) (10.44 g, 48.1%). Furthermore, the fraction contained the starting material was reacted in sealed tube again.
