Versuchsvorschrift

To a solution of 1-(2,4-dichloro-3-hydroxymethylphenyl)-2-[(E)-3-[6-[(E)-2-(pyridin-4-yl)vinyl]pyridin-3-yl]acryloylaminomethyl]pyrrole (70 mg) and triethylamine (28 mg) in N,N-dimethylformamide (1 ml) was added methanesulfonyl chloride (16.7 mg) under ice-cooling, and the mixture was stirred for 30 minutes at the same temperature. To the mixture were added 3-bromo-8-hydroxy-2-methylimidazo[1,2-a]pyridine (31.4 mg) and potassium carbonate (95.7 mg) at ambient temperature, and the mixture was stirred at the same temperature overnight. Water was added thereto, the resulting precipitates were collected by filtration. The residue was purified by preparative thin layer chromatography (chloroform:methanol=10:1, V/V) to give 1-(3-(3-bromo-2-methylimidazo[1,2-a]pyridin-8-yloxymethyl)-2,4-dichlorophenyl]-2-[(E)-3-[6-[(E)-2-(pyridin-4-yl)vinyl]pyridin-3-yl]acryloylaminomethyl]pyrrole (76 mg) as yellow amorphous.
