Reaction Steps

To a mixture of 8-[3-[N-[(E)-3-(6-carboxypyridin-3-yl)-acryloylglycyl]-N-methylamino]-2,6-dichlorobenzyloxy]-2-methylquinoline (100 mg), 2-aminopyrazine (19.7 mg) and N,N-dimethylformamide (2 ml) were added 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (43 mg) and 1-hydroxybenzotriazole (35 mg), and the mixture was stirred for 36 hours at ambient temperature. The mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with water, saturated sodium bicarbonate solution and brine, dried over magnesium sulfate, and concentrated in vacuo. The residue was purified by preparative thin-layer chromatography (methylene chloride--methanol) to give 8-[2,6-dichloro-3-[N-methyl-N-[(E)-3-[6-(2-pyrazinylcarbamoyl)-pyridin-3-yl]acryloylglycyl]amino]benzyloxy]-2-methylquinoline (21 mg) as an amorphous powder.
