Reaction Steps
54.2 g of 4-hydroxymethylbenzaldehyde, together with 40 g of triethylamine, are dissolved in 350 ml of dichloromethane. After the dropwise addition of 31.2 g of acetyl chloride at 0° to 5° C., the reaction mixture is allowed to stand overnight at room temperature. Thereafter, the precipitated triethylammonium chloride is filtered off under suction, and the filtrate is extracted 3 times with saturated bicarbonate solution. After it has been dried with sodium sulphate, the residue is distilled in a high vacuum. 47.9 g of a colorless solid are obtained in this manner.
