Procedure

A solution of 4.1 g. of potassium hydroxide (85%) in 100 ml. of alcohol was added to a solution of 18.1 g. of 7-chlorodibenzothiophene-3-carboxylic acid ethyl ester in 450 ml. of warm ethanol. The combined solutions were stirred and refluxed for 8 hours. After cooling to room temperature, the mixture was filtered to give 16.5 g. of the potassium salt.
