反応手順

4.5 ml chlorosulfonic acid were added in one portion to 6.5 g 5-Chloro-2-methoxy-N-phenethyl-benzamide. The reaction mixture was stirred at room temperature for one hour, then 100 ml dichloromethane were added and the reaction mixture was poured on ice water. The organic layer was separated washed twice with 50 ml brine and then dried over MgSO4. The solvent was removed in vacuo to obtain 5.53 g 4-[2-(5-Chloro-2-methoxy-benzoylamino)-ethyl]-benzenesulfonyl chloride.
