YieldReaction ConditionsOperation in experiment
To a solution of the compound 3, 4-DIHYDROXY BENZALDEHYDE (commercially available) (0.072 mole) in dimethylformamide (70 mL), BENZYLTRIETHYL ammonium chloride (0.036 mole) was added. To the resulting reaction mixture was added sodium hydroxide solution (0.0018 mole of 30% solution) dropwise for about 3 minutes with a continuous flow of chloro- difluoro methane. The reaction mixture was acidified with dilute hydrochloric acid and diluted with water. The reaction mixture was extracted with ethyl acetate, washed with saturated solution of sodium chloride and concentrated under reduced pressure. The residue thus obtained was purified by column chromatography to furnish the title compounds.
