Reaction Steps
A mixture of 5-(2-bromo-acetyl)-2-chloro-benzoic acid methyl ester (25 mg, 0.09 mmol) and thioacetamide (6.5 mg, 0.08 mmol) in ethanol (2 mL) and stirred at 50° C. for 15 minutes. The mixture was cooled to room temperature and concentrated in vacuo. The residue was dissolved in ethyl acetate, washed with water, and brine, dried over sodium sulfate, filtered and concentrated in vacuo to afford the title compound (10 mg).
