Reaction Steps

To a solution of 3.5 mL (3.54 g, 58 mmol) of ethanolamine in 20 mL of THF and 5 mL of water, was added 10.7 mL of triethylamine. After cooling in an ice bath, 10.53 g (51 mmol) of para-methoxybenzenesulfonyl chloride was slowly added over ten minutes. After stirring at room temperature for 1 hour, the solvent was removed under reduced pressure and ethyl acetate and water added. The organic layer was separated, washed with 5% KHSO4 and brine, dried over sodium sulfate, filtered and stripped to afford 10.3 g of the desired N-(2-hydroxyethyl)-4-methoxybenzenesulfonamide, m/e=238 (M+Li).
