Participants

Reaction Steps

A mixture of 1,2-diamino-4-nitrobenzene (31 g, 0.2 mol) and 2-furancarboxaldehyde (25 g, 0.26 mol) in 2-propanol is treated with p-benzoquinone (24 g, 0.22 mol). The reaction mixture is heated under reflux for 2 h. The reaction solution is diluted with water to precipitate the product. After drying, the crude product weighs 46 g (100%). Recrystllization from nitromethane provides an analytical sample which melts at 228°-229° C. Anal. Calcd for C11H7N3O3 ; C, 57.64; H, 3.08; N, 18.34. Found: C, 57.55; H, 3.04; N, 18.53.
