実験手順

To a stirring solution of N-octyl-3,4-dimethoxybenzenesulfonamide (0.213 g, 0.646 mmol) in 2.00 mL of DMF, NaH (0.028 g, 0.711 mmol; 60% in oil dispersion) was added. After 30 min, benzoyl chloride (0.085 g, 0.731 mmol) was added. After a further 1 hr, the reaction mixture was diluted with 4:1 EtOAc/hexanes and washed with water (2×). The organic layer was dried over MgSO4 and concentrated in vacuo to yield a yellow solid. Purification by flash chromatography (28% ethyl acetate/hexanes) gave 0.040 g (18%) of the title compound as a clear oil.
