1H-Indole-7-carboxylic acid → 1H-Indole-7-carboxylic acid (4-tert-butyl-benzyl)-[2-(ethyl-m-tolyl-amino)-ethyl]-amide

Participants

Reaction Steps

81 mg (0.50 mol) of 1H-indole-7-carboxylic acid, 162 mg (0.5 mmol) of N′-(4-tert-butyl-benzyl)-N-ethyl-N-m-tolyl-ethane-1,2-diamine and 108 mg (0.55 mmol) of EDC.HCl were dissolved in 5 ml DCM. The reaction mixture was stirred at rt over night. The solvent was evaporated and the residue was dissolved in diethyl ether. The organic layer was washed with 1N aqueous HCl solution, once with 1N aqueous NaOH solution and once with saturated aqueous NaCl solution, dried over sodium sulfate, filtered and the solvent was evaporated to leave 140 mg (55%) product as a colorless oil. MS (ISP) 468.4 (M+H)+.
