PROCEDURE

实验过程

To a solution of 4-[3-[N-[(E)-3-(6-acetamidopyridin-3-yl)acryloylglycyl]-N-methylamino]-2,6-dichlorobenzyloxy]-2-methoxy-1H-benzimidazole (100 mg) and 2-dimethylaminoethyl chloride hydrochloride (25.6 mg) in N,N-dimethylformamide (2 ml) was added potassium carbonate (92.5 mg) at ambient temperature, and the mixture was stirred for 28 hours at the same temperature. The reaction mixture was poured into water, and extracted with chloroform. The extract was washed with water and brine, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin layer chromatography to give 4-[3-[N-[(E)-3-(6-acetamidopyridin-3-yl)acryloylglycyl]-N-methylamino]-2,6-dichlorobenzyloxy]-2-methoxy-1-(2-dimethylaminoethyl)-1H-benzimidazole (11 mg) and 7-[3-[N-[(E)-3-(6-acetamidopyridin-3-yl)acryloylglycyl]-N-methylamino]-2,6-dichlorobenzyloxy]-2-methoxy-1-(2-dimethylaminoethyl)-1H-benzimidazole (38 mg).
