Reaktionsschritte

A suspension of pyrazole (1 g) and 4-toluenesulfonyl chloride (2.8 g) in pyridine (10 ml) was stirred at 130° C. for 1 hour. After the reaction mixture was cooled, water was added to the reaction mixture, resulting in a white suspension. The resultant suspension was filtered, and the obtained white solids were washed three times with water. Drying at room temperature under reduced pressure gave white solids (500 mg).
