Reaction Conditions

Reaction Steps

A stirred mixture containing 108 g. (710 mmol.) of 3-hydroxy-4-methoxybenzaldehyde, 500 ml. of chloroform, and 125 ml. of collidine was kept below 10° C., treated dropwise with 70 ml. (800 mmol.) of chloroacetyl chloride over a 1-hour period, and then stirred 2 hours at 25° C. The solution was serially extracted with 500-ml. portions of water, 0.3N HCl, and water (2×). Chloroform was evaporated and crude 3-chloroacetoxy-4-methoxybenzaldehyde was recrystallized from diethyl ether (147 g., 91%), m.p. 88°-89° C.
