Versuchsvorschrift

A mixture of 3-[(5-methyl-2-m-tolyl-4-imidazolyl)-methylene]carbazic acid, methyl ester (5.1 g, 0.019 mole) and o-dichlorobezene (75 ml) is heated slowly (45 minutes) to reflux, refluxed for 1.5 hours, then stirred at room temperature over night (appr. 15-16 hours). The reaction mixture is filtered to afford 3.9 g (0.016 mole) title product. Recrystallization from o-dichlorobenzene yields partially solvated product, m.p. 188°-198° C.
