1,3-Propanediamine, N'-(ethylcarbonimidoyl)-N,N-dimethyl-, monohydrochloride → N-[3-(4,5-dimethyl-imidazol-1-yl)-phenyl]-2,3-dimethyl-1H-indole-7-carboxamide

Participants

Reaction Steps

To a suspension of 2,3-dimethyl-1H-indole-7-carboxylic acid (95 mg) and 3-(4,5-dimethylimidazol-1-yl)aniline (94 mg) in dichloromethane (2 ml) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (135 mg) and 4-dimethylaminopyridine (31 mg), and the mixture was stirred for 12 hours. The mixture was diluted with dichloromethane and washed with water and brine. The mixture was dried over magnesium sulfate and evaporated under reduced pressure. The residue was triturated with dichloromethane, and the insoluble material was collected by filtration and dried to give N-[3-(4,5-dimethyl-imidazol-1-yl)-phenyl]-2,3-dimethyl-1H-indole-7-carboxamide (77 mg, 43.0%).
