Reaction Steps
256 g (2 mols) of 2-methyl-3-hydroxymethyl-pent-1-en-4-one were boiled for three hours under reflux with 1,000 ml of acetic anhydride. The acetic acid produced, and the excess acetic anhydride, were than distilled off in a waterpump vacuum. The residue was distilled in a high vacuum. 249 g of 2-methyl-3-acetoxymethyl-pent-1-en-4-one of boiling point 52° - 55° C/0.05 mm Hg were obtained.
