a solution consisting of propionyl chloride (64.7 g, 0.7 mol) and hydroxyacetic acid (19.0 g, 0.25 mol) is heated at 40° C., until the hydroxyacetic acid has completely dissolved. The excess propionyl chloride is then distilled off and 35.6 g of crude product containing 82% of (propionyloxy)acetic acid is obtained as a colorless liquid. The crude product can be used in the subsequent reaction without further purification.
