Hydrochloric Acid → HCID 89975555, compound

Participants

Reaction Steps

0.64 g of sodium tetrahydroborate was added to a solution of 1.2 g of 5-methyl-4-phenyloxolane-2-one in 2 mL of ethanol and 20 mL of tetrahydrofuran in a nitrogen atmosphere at a temperature of 5° C. to 10° C., and thereafter, a solution of 2.0 g of calcium chloride in 8 mL of ethanol was added dropwise to the mixture. The obtained mixture was stirred at room temperature for 200 minutes. Thereafter, 30 mL of ethyl acetate was added to the reaction mixture, and thereafter, 20 mL of 3 mol/L hydrochloric acid was added dropwise to the mixture. The organic layer was fractionated, and it was washed with a saturated sodium hydrogen carbonate aqueous solution and was then dried over anhydrous magnesium sulfate. The solvent was distilled away under reduced pressure, so as to obtain 1.05 g of 3-phenylpentane-1,4-diol in the form of a colorless oily product.
