Into a 50 mL round bottom flask, was placed 2-(2-(3-((3-tert-butoxy-3-oxopropylthio)methyl)benzamido)-5-(piperidin-1-yl)phenyl)isonicotinic acid (220 mg, 0.38 mmol, 1.00 equiv), 3-(trifluoromethyl)benzylamine (134 mg, 0.77 mmol, 2.00 equiv), EDC.HCl (124 mg, 0.63 mmol, 1.65 equiv), 4-dimethylaminopyridine (76 mg, 0.62 mmol, 1.63 equiv), and dichloromethane (10 mL). The resulting solution was stirred overnight at room temperature. The reaction progress was monitored by LCMS. The resulting mixture was washed with 5×30 mL of aqueous NH4Cl. The mixture was dried over anhydrous sodium sulfate and concentrated under vacuum. This resulted in 360 mg (90%) of tert-butyl 3-(3-((2-(4-((3-(trifluoromethyl)benzyl)carbamoyl)pyridin-2-yl)-4-(piperidin-1-yl)phenyl)carbamoyl)benzylthio)propanoate as yellow oil.
