Procedure

2-Chloroethanesulfinyl chloride (16.2 w), prepared as in Example I was dissolved in dry ether (130 v) and the solution was cooled to -15°. Normal butanol was added dropwise under a nitrogen atmosphere to the cooled solution. Upon completion of the addition period the reaction mixture was allowed to warm to ambient temperatures and the solvent was removed by distillation in a vacuum to yield a colorless liquid, butyl 2-chloroethanesulfinate (18.5 w).
