Participants

Reaction Steps

51.1 A mixture of 2.5 g 1-(2-methoxybenzyl)-4-(3-nitrophenyl)-1H-imidazole-2-ylamine (7.7 mmol, Example 45), 2.5 g activated carbon, 30 mg iron(III) chloride (in the form of the hexahydrate) in 100 mL methanol, and 20 mL acetonitrile was heated at reflux, slowly combined with 50 mL hydrazine, and then stirred for an additional 2 hr under reflux. The batch was filtered, concentrated, taken up in acetic ethyl ester, extracted with water, and the organic phase was dried (Na2SO4) and concentrated. The residue thus obtained was mixed with acetic ethyl ester, suctioned off, and dried (2 g target product).
