To a solution of 3-(mercaptomethyl)benzoic acid (500 mg, 2.97 mmol, 1.00 equiv) in acetonitrile (10.0 mL) was added methyl acrylate (10.0 mL) and 1,8-Diazabicyclo[5.4.0]undec-7-ene (1.0 g, 6.57 mmol, 2.00 equiv) and the resulting solution was heated to reflux overnight. The reaction was concentrated under vacuum and the residue was applied onto a silica gel column with ethyl acetate/petroleum ether (0˜1:6) to afford 220 mg (28%) of 3-((3-methoxy-3-oxopropylthio)methyl)benzoic acid as light-red oil.
