Reaction Conditions

Reaction Steps

To a solution of 2,4-thiazolidinedione (3.50 g, 30.0 mmol) in ethanol (120 mL) was added 3-hydroxy-4-nitrobenzaldehyde (5.00 g, 30.0 mmol) and piperidine (0.44 mL, 4.50 mmol). The mixture was stirred at reflux for 15 hours and then cooled to 0° C. The resulting precipitate was collected and washed with cold ethanol to afford 3.53 g of the desired compound as a brown solid. Further concentration and precipitation of the mother liquor afforded an additional 3.1 g of the product. This was used without further purification in the next reaction. 1H NMR (CDCl3)·8.20 (1H, d, J=8.8 Hz), 7.75 (1H, s), 7.26 (1H, s), 7.12 (1H, d, J=8.8 Hz).
