実験手順

In a 50 mL round-bottom flask a mixture of 50 (0.5 g, 002 mol), 2-hydroxy-3 methoxybenzaldehyde (0.4 g, 0.0025 mol) and NaOAc (0.233 g, 0.002 mol) in AcOH was heated under reflux for 10 hours. After cooling the precipitate formed was filtered off, washed with water, dried and recrystallized from acetic acid to yield 51 (0.74 g, 85%). M. Wt. 384. LCMS [M+H]+=385.
