Procedure

To a mixture of 2.01 g of diethyl[3-(1,3-dioxolan-2-yl)phenyl]malonate, 2.89 g of calcium chloride, and 50 ml of ethanol was added 2.47 g of sodium borohydride under ice-cooling, followed by stirring at the same temperature for 2 hours and at room temperature for 4 hours. To the reaction solution was added 10 ml of water at room temperature, followed by stirring for 30 minutes. The insoluble material was separated by filtration using Celite, and the filtrate was concentrated under reduced pressure to obtain 0.76 g of 2-[3-(1,3-dioxolan-2-yl)phenyl]propane-1,3-diol as a colorless oily substance.
