Reaction Steps

3-(3,5-Bis(trifluoromethyl)phenethyl)-4-benzyl-1-(3-aminopropyl)-5-oxo-1,2,4-triazole (Example 2, 0.500 g, 0.0010 mol) was dissolved in dichloromethane (20 ml) and indole-3-acetic acid (0.222 g, 0.00127 mol), 1-(3-dimethylamino-propyl)-3-ethylcarbodiimide.HCl (0.244 g, 0.00127 mol), hydroxybenzotriazole (0.171 g, 0.00127 mol) and triethylamine (0.7 ml, 0.005 mol) added. The reaction was stirred for 16 hours, diluted with ethyl acetate (50 ml), washed with 10% citric acid solution, saturated sodium bicarbonate solution and brine. The organic layer was dried (MgSO4) and solvent evaporated. The residue was chromatographed on silica eluting with ethyl acetate then 1% methanol/ethyl acetate, to give the title compound as a pale yellow solid (0.500 g 80%).
