Versuchsvorschrift

In 30 ml of dry dimethylformamide was suspended 2.18 g of 2-methylimidazo[2,1-b]benzothiazole-3-methanol. Then, 0.50 g of 60% sodium hydride was added to the suspension. After stirring for 30 minutes, 1.76 g of thenoyl chloride was added to the mixture followed by stirring at room temperature for 3 hours. Ice water was added to the reaction mixture and the system extracted with chloroform. After the chloroform was removed, 1.76 g of the title compound was obtained.
