Acetyl chloride → HCID 20295047, compound

Participants

Reaction Steps

A mixture of acetyl chloride (77 g) and thionyl chloride (0.8 ml) was added, with stirring, to 3,4-dichlorobenzaldehyde dimethyl acetal (110 g). The mixture was kept at laboratory temperature (about 27° C.) for 22 hours and then evaporated at 30° C. under reduced pressure (0.15 mm Hg) for about 4 hours until constant in weight. 3,4-Dichloro-α-methoxybenzyl chloride (112 g) was thus obtained as an oil, which was used without further purification as a starting material in the above preparations.
