Participants

Reaction Steps

To a solution of benzyl 4-[3-(3-benzylaminobenzoyl)-indol-1-yl]butyrate (88 mg) and diisopropylethylamine (45 mg) in dichloromethane (3 ml) was added a solution of 1-bromo-1-(4-isobutylphenyl)propane (90 mg) in dichloromethane (1 ml). The mixture was stirred at room temperature for 24 hours and evaporated. The residue was dissolved in ethyl acetate. The solution was washed with water, dried over magnesium sulfate and evaporated. The residue was chromatographed on silica gel (5 g) eluting with a mixture of n-hexane and ethyl acetate (4:1) to give benzyl 4-[3-[3-[N-benzyl-N-[1-(4-isobutylphenyl)propyl]-amino]benzyl]indol-1-yl]butyrate (30 mg) as an oil.
