1-(1-(4-chlorobenzyl)-1H-indole-2-carbonyl)piperidine-4-carboxylic acid (390 mg, 0.982 mmol), 1-hydroxybenzotriazole (221 mg, 1.637 mmol) and EDCI (314 mg, 1.637 mmol) were dissolved in DCM (Volume: 4.0 ml). The suspension was stirred at room temperature for 10 minutes where it turned clear. Hunig's Base (0.286 ml, 1.637 mmol) and 2-(pyridin-4-yl)ethanamine (0.098 ml, 0.819 mmol) were added. The reaction was stirred at room temperature overnight. The reaction was concentrated and triturated with ethyl acetate to afford the product as a white solid. Yield: 328 mg (White solid) 1H-NMR (500 MHz, DMSO-d6) 8.46, 7.91, 7.63, 7.55, 7.34, 7.25-7.18, 7.14-7.06, 6.72, 5.49, 4.54-3.80, 3.32, 3.07-2.77, 2.73, 2.37-2.28, 1.77-1.18.
