Participants

Reaction Steps

To a suspension of 1.9 g. of 7-dimethylaminodibenzothiophene-3-carboxylic acid potassium salt in 100 ml. of refluxing benzene was added over a period of 20 minutes a solution of 1.2 g. of oxalyl chloride in 25 ml. of benzene. The solution was then stirred and refluxed for 3 hours. The hot solution was filtered, and the filtrate was distilled to dryness in vacuo (steam bath, rotary evaporator).
