Versuchsvorschrift
The mixture of methyl cyanoacetimidate hydrochloride (43.47 g, 0.32 mole) and 4-nitro-2-aminophenol (24.9 g, 0.16 mole) in methanol (260 ml) was heated at reflux for 3 h. The mixture was placed in an ice bath for 30 minutes and was filtered. The solid material was suspended in water (300 ml), stirred for a few minutes and filtered. It was washed with water (200 ml) and air dried to give 4-nitro-2-benzoxazoleacetonitrile (27.38 g, 83%).
