Reaction Steps
A solution of 4-[2-(N-methyl-N-(2-pyrimidinyl)amino)ethoxy]benzaldehyde (1.7 g) and 2,4-thiazolidinedione (0.7 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 to give the title compound (mp 189°-90° C.).
