Reaction Steps

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