反応手順

1.72 g of methyl 4-formyl-3-methoxybenzoate was dissolved in 8.6 mL of methanol, to which 2.6 mL of a 20% aqueous solution of sodium hydroxide was added at room temperature, and this solution was stirred for one hour at the same temperature. The reaction mixture, to which water was added, was adjusted to pH 2 with 6M hydrochloric acid, and resultant precipitate was filtered out therefrom and washed with water to yield 1.49 g of 4-formyl-3-methoxybenzoic acid as light yellow solid.
