The thiazolidine compound, cas is 1438-16-0 name is 3-Aminorhodanine, mainly used in chemical industry, its synthesis route is as follows.

General procedure: A mixture of aminorhodanine (1 mmol), isatin (1 mmol) and 5 muL of acetic acid in 2mL of distilled ethanol was placed in a cylindrical quartz reactor (Phi = 4 cm). The reactor was introducedinto a monomode microwave (Anton Paar) apparatus, for 5 min at100 C and 50 Watts. The crude reaction mixture was allowed tocool down at room temperature and ethanol (10 mL) or mixture of H2O/EtOH (10 mL) was directly added in the cylindrical quartzreactor. The resulting precipitated product was filtered off and waspurified by recrystallization from ethanol if necessary.
