Procedure

A mixture of 4-hydroxy-2-methoxy-1-methyl-1H-benzimidazole (47.4 mg), 2-[(E)-3-(6-acetamidopyridin-3-yl)acryloylaminomethyl]-1-[2,4-dichloro-3-(methanesulfonyloxymethyl)phenyl]pyrrole (143 mg) and potassium carbonate (110 mg) in N,N-dimethylformamide (4 ml) was stirred at ambient temperature for 3.5 days. The mixture was partitioned between chloroform and water. The separated organic layer was dried over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin layer chromatography (chloroform:methanol=9:1, V/V) to give 2-[(E)-3-(6-acetamidopyridin-3-yl)acryloylaminomethyl]-1-[2,4-dichloro-3-(2-methoxy-1-methyl-1H-benzimidazol-4-yloxymethyl)phenyl]pyrrole (39 mg) as colorless crystals.
