実験手順
The 5-benzenesulfonyloxybenzo[b]thiophene-3-carboxylic acid (12) (5.582 g, 16.7 mmol) prepared above was refluxed with dimethylformamide (1 drop), thionyl chloride (3.57 ml, 50 mmol) and toluene (22 ml) for 1.5 hours. When the solvent was removed under reduced pressure, 5.89 g of the objective compound (6) was obtained.
