A solution of 2.33 g (9.4 mmoles) of acetoxymethyl 1,3-diacetoxy-2-propyl ether in 22 ml of sieve-dried methylene chloride was stirred at room temperature while a slow stream of anhydrous hydrogen chloride was passed through the solution. Anhydrous conditions were maintained throughout the reaction. After two hours the reaction was judged to be complete by nuclear magnetic resonance spectroscopy. The reaction mixture was purged with nitrogen and concentrated in vacuo. The residue was taken up in a small volume of toluene and concentrated in vacuo. This was repeated twice and then the residue was pumped in vacuo to remove residual solvent. The yield of chloromethyl 1,3-diacetoxy-2-propyl ether is 1.92 g (91%).
