Versuchsvorschrift
A solution of 60 g (0.103 mol) of 2,2-bis-(4-mesyloxy-3-nitrophenyl)-hexafluoropropane and 122.8 g (1.32 mol) of aniline in 400 ml of acetonitrile is heated under reflux for 24 hours. In the course of this the methanesulfonic acid salt of aniline is precipitated, and is removed by filtration with suction. The filtrate is freed from the solvent and from excess aniline by distillation under reduced pressure. Recrystallizing the residue from ethanol gives 47.3 g of 2,2-bis-(4-anilino-3-nitrophenyl)-hexafluoropropane (80% yield). M.p. 165-166° C.
