Procedure

To a solution of 0.5 g. of potassium hydroxide in 100 ml. of ethanol was added 2.8 g. of 7-dimethylaminodibenzothiophene-3-carboxylic acid ethyl ester. The solution was stirred and refluxed for 3 hours during which time the potassium salt precipitated. The salt was filtered off, washed with ether and air dried. The yield of 7-dimethylaminodibenzothiophene-3-carboxylic acid potassium salt was 1.9 g.
