Participants

Reaction Steps

A mixture of methyl 3-bromo-4-chlorobenzo[b]thiophene-2-carboxylate (0.62 g, 2.0 mmol) , 2-propanethiol (0.30 mL, 0.25 g, 3.2 mmol) , and 1,8-diazabicyclo[5.4.0]undec-7-ene (0.33 mL, 0.34 g, 2.2 mmol) in 5.0 mL of N,N-dimethylformamide is stirred at room temperature for 24 hours. The reaction mixture is partitioned between 150 mL of cold 1.0N HCl and 75 mL of dichloromethane, and the aqueous layer is extracted several times with fresh dichloromethane. The combined organic layers are washed with 1.0N HCl and brine, then dried (anhydrous sodium sulfate) and evaporated to yield methyl 4-chloro-3-[(1-methylethyl)thio]benzo[b]thiophene-2-carboxylate as an oil.
