Reaction Steps

A mixture of 5-bromothiophene-2-sulfonyl chloride (1 g, 3.82 mmol) and 2-methoxyethanamine (0.43 g, 5.73 mmol, 1.5 eq) in 1,4-dioxane (20 mL) was stirred at r.t. for 2.5 h. The mixture was evaporated under reduced pressure. The residue was purified by column chromatography (PE100%-EtOAc100%) to afford 5-bromo-N-(2-methoxyethyl)thiophene-2-sulfonamide (1 g, 87%). LC-MS (m/z)=301 [M+H]+.
