Procedure

Piperidine (0.019 mL) was added to an ethanol (2 mL) solution of 3-methoxy-4-(4-methyl-1H-imidazol-1-yl)benzaldehyde (20 mg) obtained in Example 1 and 3-(4-methoxyphenyl)-2-thioxoimidazolidine-4-one (21 mg), and heat-refluxing of the reaction solution was carried out for 12 hours. The reaction solution was allowed to be cooled to room temperature and the solid deposited was separated by filtering, and 18 mg (47%) of the title compound was obtained by washing with ethanol and ether. The physical properties of the compound are as follows.
