Participants

Reaction Steps

38 g (100 mmol) of the benzyl (S)-2-hydroxy-3-methoxy-3,3-diphenylpropionate were added to 9.8 g (130 mmol) of glycolic acid, and the mixture was stirred with 300 mg of anhydrous para-toluenesulfonic acid at 70° C. on a rotary evaporator under reduced pressure for 20 minutes. The content of the flask was taken up in dichloromethane, the acid was separated off using sodium hydrogen sulfate solution, the organic phase was separated off and dried and the solvent was distilled off. The residue was recrystallized from ether, and 21 g (54 mmol) of product were isolated.
