To a room temperature solution of 2-[(2,6-dichloro-3-methylphenyl)amino]benzaldehyde (276 mg, 0.99 mmols) and 3-methylrhodanine (166 mg, 1.13 mmols) in 15 mL of acetic acid is added β-alanine (102 mg, 1.14 mmols). The solution is heated at reflux for 3.5 h. The solution is cooled to room temperature and the resulting precipitate is collected by filtration to provide 258 mg (64%) of (Z)-5-[[2-[(2,6-dichloro-3-methylphenyl)amino]phenyl]methylene]-2-thioxo-4-thiazolidinone as a bright orange solid; mp=175°-176° C. Calc'd for C18H14Cl2N2OS2:

1. temperatureThe solution is heated
