Reaction Conditions

Temperature23 °C

Reaction Steps

A solution of 5.5 g (27.5 mmol) of 5-chlorothiophenesulfonyl chloride in dry THF at 0° C. was treated with a solution of 5.7 mL (75.5 mmol) of t-butylamine. After warming to 23° C., the reaction mixture was diluted with 125 mL of diethyl ether, filtered, and washed with 1 N HCl, brine, and dried (MgSO4). Concentration in vacuo affords 6.4 g (98%) of the named compound as an oil.
