A mixture of 12.2 g of 2-fluorobenzaldehyde, 15 ml of 2,2-dimethoxypropane and 0.1 g of 4-toluenesulphonic acid was stirred at room temperature. After 24 hours, diethyl ether was added and the resultant solution washed with saturated sodium bicarbonate solution. Drying and evaporation of the organic phase gave the crude acetal. Distillation under vacuum at 90°-95° C./0.08 mm yielded the title compound as a colourless oil.
