Fluorene-1-carboxylic acid → N-[3-(4-methylimidazol-1-yl)-phenyl]-9H-fluorene-1-carboxamide

Participants

Reaction Steps

To a suspension of 9H-fluorene-1-carboxylic acid (79 mg) and 3-(4-methylimidazol-1-yl)aniline (65 mg) in dichloromethane (2 ml) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (101 mg) and 4-dimethylaminopyridine (23 mg), and the mire was stirred for 24 hours. The mix e was diluted with dichloromethane, washed with water and brine. The mixture was dried over magnesium sulfate and evaporated under reduced pressure. The residue was triturated with methanol, and the insoluble material was collected by filtration and dried to give N-[3-(4-methylimidazol-1-yl)-phenyl]-9H-fluorene-1-carboxamide (40 mg, 29.2%).
