Yield:35432-36-1 95%

Reaction Conditions:

Stage #1:2-methylpropanethiol-1 with sulfuryl dichloride;potassium nitrate in acetonitrile at 0; for 3 h;
Stage #2: with sodium hydrogencarbonate in water;acetonitrile

Steps:

2-Methyl-1-propanesulfonyl chloride
To [2-METHYL-1-PROPANETHIOL] (200 mg, 2.22 mmol) at [0C] in acetonitrile under nitrogen was added [KNOWS] (561 mg, 5.5 mmol) then sulfuryl chloride (0.45 ml, 5.5 mmol). The reaction mixture was stirred at [0C] for 3h, diluted with [NAHCO3] and extracted with ethyl acetate. The combined organic layers were washed with brine, dried [(MGS04)] and evaporated to give the sulfonyl chloride (293 mg, 95%)
