A solution of 18.7 g of 2-(3-benzyloxypropyl)-3-hydroxy-γ-butyrolactone in 90 ml of ethanol-acetic acid (2:1) is hydrogenated over 640 mg of 10% palladium on carbon at 45 psi for 20 h. The catalyst is filtered and the filtrates are evaporated to give 2-(3-hydroxypropyl)-3-hydroxy-γ-butyrolactone as an oil.
