実験手順

Bifonazole has also been prepared by benzoylation of imidazole with PhCOCl, yielding 74.7% of 1-benzoylimidazole which is subject to react with Gringnard's reactant 4-PhC6H4MgBr followed by a tosylation and subsequent reduction with sodium cyanoborohydride in hexamethylphosphoramide, to yield 68.2% Bifonazole (Es. Patent 539,345).
