Procedure

3-{ [2-(p-nitrophenyl)-5-methyl-4-imidazolyl]-methylene}carbazic acid, methyl ester (2.5 g, 0.0082 mole) is immersed in diphenyl ether (25 ml) at 240° C for 20 minutes, then stirred in an ice bath for 1 hour. The reaction mixture is diluted with ether and filtered to afford 2.2 g (0.008 mole) title product. The product is purified via an acetone soxhlet extraction to give a yellow solid, m.p. 295°-297° C.
