Reaction Steps

The suspension of 6-quinazolinecarboxaldehyde (example 1a, 1.5 g, 9.5 mmol), rhodanine (1.26 g, 9.5 mmol) and sodium acetate (3.11 g, 38 mmol) in acetic acid (10 mL) was stirred at 130° C. for 12 h. After cooling to room temperature, water (40 mL) was added. The solid was collected by filtration, washed with water and dried to obtain 5-quinazolin-6-ylmethylene-2-thioxo-thiazolidin-4-one (2.6 g, 100%) as a solid. LC-MS m/e 274 (MH+).
