Procedure
To a solution of 2-thiopheneacetic acid (1.50 g, 10.6 mmol) in MeOH (20 mL) was added thionyl chloride (3.80 mL, 53 mmol) dropwise at 0° C. The resulting solution was stirred at room temperature for 18 h. The reaction mixture was concentrated in vacuo to give the title compound as a dark brown oil (1.65 g, quantitative yield) which was used in the next step without further purification.
