1,3-Propanediamine, N'-(ethylcarbonimidoyl)-N,N-dimethyl-, monohydrochloride → 6-Fluoro-1H-indole-7-carboxylic acid (4-tert-butyl-benzyl)-[2-(3,4-dichloro-phenyl)-ethyl]-amide

Participants

Reaction Steps

98 mg (0.55 mol) of 6-fluoro-1H-indol-7-carboxylic acid, 168 mg (0.50 mmol) of (4-tert-butyl-benzyl)-[2-(3,4-dichloro-phenyl)-ethyl]-amine and 105 mg (0.55 mmol) of EDC.HCl were dissolved in 5 ml 1,2-dichloro-ethane. The reaction mixture was stirred at rt over night and heated to 80° C. for 3 h. The solvent was evaporated and the residue was purified by column chromatography (20 g silica gel; heptane/EtOAc 4:1) to yield 108 mg (43%) product as a colorless viscous oil. MS (ISP) 497.2 (M+H)+.
