実験手順

A mixture of 3-ethoxy-2-hydroxy-6-nitrobenzaldehyde (58 g, 0.275 mole), benzyl chloride (34.8 cm3, 0.302 mole) and potassium carbonate (41.6 g, 0.302 mole) in 300 cm3 of dimethylformamide is heated for 3 hours under reflux with stirring. The reaction mixture is poured into 1 liter of iced water and the precipitate is filtered off. It is washed with water and dried. A light beige powder of 2-benzyloxy-3-ethoxy-2-nitrobenzaldehyde (72 g, yield=86%, m.p.=110°-111° C.) is obtained.
