Versuchsvorschrift

Combine 4-methyl-2-(2-nitro-phenylamino)-benzonitrile (2.46 g, 9.71 mmol), tin(II) chloride dihydrate (6.57 g, 29.71 mmol), 5N. HCl (40 ml), and ethanol (40.0 ml). Stir the mixture at reflux for 8 hours then cool it to ambient temperature. Allow the mixture to stand at ambient temperature overnight then chill it for 3 hours in the refrigerator. Remove the resulting precipitate by vacuum filtration and dry it under vacuum to give 1.24 g (49%) of the desired compound as a yellow solid: mass spectrum (ion spray): m/z=224.0 (M+1).
