Reaction Steps

tert-Butyl-thiophene sulfonamide available from Preparative Example 16.1 Step A (164 mg, 050 mmol) was treated with potassium carbonate (700 mg. 5 mmol) and iodoethane (0.4 mL 5 mmol) in acetone and refluxed for 1.5 d. The mixture was filtered, and the solid material was washed with methylene chloride. The combined filtrated and washing were concentrated purified by flash column chromatography eluting with 0 to 30% methylene chloride in hexanes. Removal of solvents afforded the ethyl-tert-butyl-sulfonamide (151 mg, 85%).
