実験手順
A mixture of 3-[(5-methyl-2-phenyl-4-imidazolyl)-methylene]carbazic acid ethyl ester (8.33 g, 0.03 mole) and diphenyl ether (60 ml) is heated with stirring at 215°-230° C for 20 minutes. The reaction mixture is cooled and diluted with petroleum ether (340 ml). The precipitate is collected and recrystallized from benzene (350 ml) to yield the title product, m.p. 182°-184.5° C.
