Versuchsvorschrift
To a mixture of (5-chloro-2-oxo-1,3-benzothiazol-3(2H)-yl)acetic acid (731 mg), 1-(1H-benzimidazol-2-yl)-N-methylmethanamine dihydrochloride (736 mg), and dichloromethane (20 mL) were added HOBt (448 mg), WSC.HCl (633 mg), and TEA (1.05 mL), followed by stirring at room temperature overnight. The resulting solid was collected by filtration and then washed with chloroform to obtain N-(1H-benzimidazol-2-ylmethyl)-2-(5-chloro-2-oxo-1,3-benzothiazol-3(2H)-yl)-N-methylacetamide (925 mg).
