Oxalyl chloride → Methyl 3-(3-(chlorocarbonyl)benzylthio)propanoate

Participants

Reaction Steps

To a solution of 3-((3-methoxy-3-oxopropylthio)methyl)benzoic acid (61.6 mg, 0.24 mmol, 1.00 equiv) in dichloromethane (5 mL) was added dropwise oxalyl dichloride (121.76 mg, 0.96 mmol, 4.00 equiv) followed by a few drops of N,N-dimethylformamide. The resulting solution was heated to reflux for 30 min, then concentrated under vacuum to afford 60 mg (crude) of methyl 3-(3-(chlorocarbonyl)benzylthio)propanoate as a yellow oil.
