Procedure

3-{[2-(p-nitrophenyl)-5-methyl-4-imidazolyl]methylene}carbazic acid, methyl ester (2.5 gm., 0.082 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 gm. (0.008 mole) title product. The product is purified via an acetone soxhlet extraction to give a yellow solid, m.p. 295°-297° C.
