1-Hydroxybenzotriazole → HCID 54321652, compound

Participants

Reaction Steps

To a solution of 8-[3-(N-glycyl-N-methylamino)-2,6-dichlorobenzyloxy]-4-(imidazol-1-yl)-2-methylquinoline (80 mg), 4-(dimethylcarbamoyl)cinnamic acid (41 mg) and 1-hydroxybenzotriazole (29.9 mg) in dichloromethane (0.8 ml) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (39.1 mg) at ambient temperature, and the mixture was stirred for 3 hours at the same temperature. To the mixture was added saturated sodium bicarbonate solution, and the separated organic layer was dried over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin layer chromatography (chloroform:methanol, 10:1, v/v) to give 8-[2,6-dichloro-3-[N-[4-(dimethylcarbamoyl)cinnamoylglycyl]-N-methylamino]benzyloxy]-4-(imidazol-1-yl)-2-methylquinoline (104 mg) as colorless amorphous.
