Procedure

To a mixture of 2-[(E)-3-(6-acetamidopyridin-3-yl)acryloylaminomethyl]-3-(2,4-dimethyl-3-hydroxymethylphenyl)thiophene (45 mg) and triethylamine (13.6 mg) in N,N-dimethylformamide (2 ml) was added methanesulfonyl chloride (14.2 mg) under ice-cooling, and the mixture was stirred for 1 hour at the same temperature and for 5 hours at ambient temperature. The mixture was poured into water and extracted with chloroform. The organic layer was washed with water and brine, dried over magnesium sulfate and evaporated in vacuo to give a residue containing 2-[(E)-3-(6-acetamidopyridin-3-yl)acryloylaminomethyl]-3-(2,4-dimethyl-3-chloromethylphenyl)thiophene. To a mixture of 8-hydroxy-2-methylquinoline (14.8 mg) and potassium carbonate (39 mg) in N,N-dimethylformamide (0.5 ml) was added a solution of the residue obtained above in N,N-dimethylformamide (1.5 ml) at ambient temperature, and the mixture was stirred for 6 hours at 50° C. The mixture was poured into water and extracted with chloroform. The organic layer was washed with water and brine, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin layer chromatography (chloroform:methanol=20:1, V/V) to give 2-[(E)-3-(6-acetamidopyridin-3-yl)acryloylaminomethyl]-3-[2,4-dimethyl-3-(2-methylquinolin-8-yloxymethyl)phenyl]thiophene (26 mg) as amorphous powder.
