Yield:-

Reaction Conditions:

with thionyl chloride

Steps:

1.a (a)
(a) 141 g (1.7 mol) of acetyl chloride were added dropwise to 76 g (1 mol) of anhydrous hydroxyacetic acid at 20° to 30° C., whereupon vigorous evolution of hydrogen chloride could be observed. The mixture was heated to a temperature of 90° to 100° C. for 3 hours; excess acetyl chloride was then distilled off. The residue was warmed to 30° C. and 174 g (1.42 mol) of thionyl chloride were added dropwise thereto. The reaction mixture was heated to the boil for 3 hours. Working up was effected by vacuum distillation. Yield: 96 g (70% of theory) of acetoxyacetylchloride, a colorless liquid of boiling point: 65° C./30 mbars. STR127
