실험 절차
Hydrogen chloride gas was introduced into a mixture of 2-acetoxyethanethiol (24.0 g) and paraformaldehyde (6.0 g) at a moderate rate with external cooling for 3 hours. Calcium chloride (25 g) was added and the reaction mixture allowed to stand in a salt-ice bath for 4 hours. Methylene chloride (200 ml) was added, the reaction mixture filtered and the solvent evaporated with rigorous exclusion of moisture. The residual oil was distilled to give 2-acetyloxyethyl chloromethyl sulfide (18.5 g, bp 82°-87° C. at 3 mm Hg).
