Reaction Steps

33.8 Grams of 4-chloro-3-sulfamoylbenzoic acid-N-methylbenzylamide (0.1 mole) were heated with 80 ml of N-methylpiperazine for 4 hours under reflux. Subsequently the solution was introduced into 0.4 l of water, the pH value of the mixture was adjusted to 9.0 by means of glacial acetic acid, and the mixture was then allowed to stand for 2 days at room temperature. The crystalline precipitate was separated and was recrystallized from a mixture of ethanol and water.
