Magnesium bromide Friedel-Crafts reaction

A number of amidines have anthelmintic activity. Bunamidine (25), indicated for treatment of human pinworm infestations, is prepared from a-naphthylhexyl-ether (23) by Friedel-Crafts type reaction with cyanogen bromide and aluminum chloride to give nitrile (24). This, then, is reacted with the magnesium bromide salt of di-n-propylamine leading to the naph-thamidine structure (25). -... [Pg.212]

Reaction IX. (a) Action of Magnesium Alkyl or Aryl Halide on certain Alkyl or Aryl Halides in the presence of Absolute Ether (Grignard). (C. 1906, II., 748.)—The Grignard reaction has perhaps a wider application than even the Friedel-Crafts or the diazo reaction. When an alkyl or aryl bromide or iodide is treated with magnesium powder, usually in presence of absolute ether, a magnesium alkyl or aryl halide is formed. [Pg.66]
