실험 절차

A solution of 2.4 g (7.2 mmol) of tert-butyl[3-(5-formylthiophen-2-yl)benzyl]methylcarbamate, 0.85 g (7.2 mmol) of 2,4-thiazolidinedione and 0.2 g (1.4 mmol) of piperidinium acetate in 50 ml of toluene is refluxed for 4 hours in Dean-Stark apparatus. After cooling, the product precipitates. The precipitate is filtered off and washed with ethyl ether. 2.3 g (76%) of tert-butyl {3-[5-(2,4-dioxothiazolidin-5-ylidenemethyl)thiophen-2-yl]benzyl}methylcarbamate are obtained.
