실험 절차

103 Grams of 4-chloro-3-sulfamoylbenzoic acid-N-methyl-2-furylmethylamide (0.3 mole) were heated under reflux with 0.3 l of N-methylpiperazine for 5 hours. After the reaction solution had been poured into 2 l of water, the pH value of the mixture was adjusted to 8.0 with 5N HCl. After standing at room temperature for 3 days, the separated yellow resin had crystallized. The reaction product was suction-filtered, washed thoroughly with water and was recrystallized from a mixture of methanol and water.
