Procedure

Into a 50-mL 3-necked round-bottom flask, was placed 2-(2-(3-((3-tert-butoxy-3-oxopropylthio)methyl)benzamido)-5-(piperidin-1-yl)phenyl)isonicotinic acid (125 mg, 0.22 mmol, 1.00 equiv), (4-(1H-pyrazol-1-yl)phenyl)methanamine (41 mg, 0.24 mmol, 1.10 equiv), EDC HCl (62 mg, 0.32 mmol, 1.50 equiv), 4-dimethylaminopyridine (40 mg, 0.33 mmol, 1.51 equiv), and dichloromethane (15 mL). The resulting solution was stirred overnight at room temperature. The resulting solution was extracted with 40 mL of dichloromethane and the organic layers combined. The resulting mixture was washed with 2×15 mL of H2O. The mixture was dried over anhydrous sodium sulfate and concentrated under vacuum. The product was obtained as 0.132 g (83%) of a yellow crude solid.
