Procedure

To a solution of 8-[3-(N-glycyl-N-methylamino)-2,6-dichlorobenzyloxy]-2-methylquinoline (81 mg) and triethylamine (0.04 ml) in dichloromethane (2 ml) was added a solution of (E)-styrenesulfonyl chloride (48 mg) in dichloromethane (1 ml) in an ice-water bath. After being stirred for 30 minutes under ice-cooling, the reaction mixture was partitioned into dichloromethane and water. The organic layer was dried over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin-layer chromatography (dichloromethane-methanol) to give 8-[2,6-dichloro-3-[N-methyl-N-((E)-styrylsulfonylglycyl)amino]benzyloxy]-2-methylquinoline (78 mg) as an amorphous powder.
