Procedure

Dissolve N-butyl-4-methyl-benzenesulfonamide (10 mmol) in tetrahydrofuran (50 mL) and add triphenylphosphine (10 mmol). Treat this with ethylene glycol (10 mmol) followed by addition of diethyl azodicarboxylate (10 mmol). Stir the reaction at 25° C. for 18 hours. Concentrate the reaction under vacuum. Purify the residue by flash chromatography (silica gel, toluene/ethyl acetate) to provide N-butyl-N-(2-hydroxy-ethyl)-4-methyl-benzenesulfonamide.
