Reaction Steps

Into 4 mL of pyridine were dissolved 120 mg of methyl 4-amino-3-methoxybenzoate and 150 mg of 5-chloro-2-chlorosulfonyl-3-methylbenzo[b]thiophene, followed by 14 hours of stirring at room temperature. After confirmation of disappearance of the starting material, the reaction was terminated by adding water at 0° C., followed by extraction with ethyl acetate. The organic layer was washed with saturated brine and then dried over anhydrous sodium sulfate. The solvent was removed by evaporation and then the residue was purified by silica gel column chromatography (chloroform/methanol=9/1) to obtain 110 mg of the title compound as colorless amorphous.
