Methacrylic Acid → 8-(2,6-Dichlorobenzoylamino)-4-(2-methacryloylhydrazino)quinoline

Participants

Reaction Steps

A mixture of 8-(2,6-dichlorobenzoylamino)-4-hydrazinoquinoline (200 mg), methacrylic acid (54.5 mg), 1-ethyl-3-(3-dimethylaminopropyl)-arbodiimide hydrochloride (133 mg) and 1-hydroxybenzotriazole (93.4 mg) in dimethylformamide (4 ml) was stirred for 4.5 hours at ambient temperature. The mixture was diluted with ethyl acetate and washed with water, saturated sodium bicarbonate solution and brine. The insoluble materials were collected by filtration and recrystallized from ethanol to give 8-(2,6-dichlorobenzoylamino)-4-(2-methacryloylhydrazino)quinoline (190 mg).
