Reaction Steps

To methyl 4-[2-(2-amino-5-chlorophenyl)-(E)-vinyl]benzoate (130 mg; prepared in Reference Example 5.) in methylene chloride (3 ml), pyridine (0.073 μl) and p-chlorobenzenesulfonylchloride (114 mg) were added. The mixture was stirred overnight at room temperature. The reaction mixture was poured into diluted HCl and extracted with ethyl acetate. The organic layer was washed, dried over and concentrated under the reduced pressure. The residue was purified on silica gel column chromatography (AcOEt-hexane) to give the title compound (205 mg) having the following physical data.
