Reaktionsschritte
A solution of 4-[2-(N-methyl-N-(2-benzothiazolyl)amino) ethoxy]benzaldehyde (1.9 g) and 2,4-thiazolidinedione (0.8 g) in toluene (100 ml) containing a catalytic quantity of piperidinium acetate was boiled under reflux in a Dean and Stark apparatus for 2 hours. The mixture was cooled and filtered and the filtered solid was dried to give the title compound (mp 219° C.).
