実験手順
An 8.33 gm. portion of 3-[(5-methyl-2-phenyl-4-imidazolyl)methylene]carbazic acid ethyl ester in 60 ml. of diphenyl ether is heated in an oil bath at 215°-230° C. for 20 minutes. The reaction mixture is diluted to 400 ml. with petroleum ether. The precipitate is collected and recrystallized from 350 ml. of benzene giving the desired product, m.p. 182°-184.5° C.
