Reaction Steps

Into a 50-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 2-(2-(3-((3-tert-butoxy-3-oxopropylthio)methyl)benzamido)-5-(piperidin-1-yl)phenyl)isonicotinic acid (170 mg, 0.30 mmol, 1.00 equiv) in dichloromethane (10 mL), and oxalyl dichloride (112 mg, 0.88 mmol, 3.00 equiv). The resulting solution was stirred for 4 h at room temperature. The resulting mixture was concentrated under vacuum to yield 200 mg of crude product a yellow solid.
