Reaction Steps

A catalytic amount of ammonium chloride was added into 100 ml acetic acid solution containing terephthaldicarboxaldehyde (1.34 g) and 3-methylrhodanine (1.53 g), followed by about 12 hours of heating at 110° C. After cooling upon standing, the formed yellow crystals were collected by filtration, washed with an appropriate amount of ethanol-water (10:1), and dried to obtain 4-(3-methyl-4-oxo-2-thioxothiazolidin-5-ylidenmethyl)benzaldehyde (1.91 g).
