Reaction Steps
To a solution of N-isobutyl-4-methoxy-benzenesulfonamide (1.03 g, 4.2 mmol) in anhydrous dimethylacetamide (20 mL) at 0° C. was added NaH (60% dispersion in mineral oil, 186 mg, 4.6 mmol) until no more gas evolved then stirred for a further 10 minutes. 4-Chlorobenzylbromide (951 mg, 4.6 mmol) was added and the reaction heated at 90° C. for 2 hours. The reaction was left to cool to room temperature, water was added, extracted with DCM, filtered through a phase separator, concentrated then purified by silica gel column chromatography (0-50% DCM in cyclohexane) to give N-(4-chloro-benzyl)-N-isobutyl-4-methoxy-benzenesulfonamide (1.03 g, 67%). LCMS (m/z, Method A)) ES+ 368 [M+1]+.
