<p>1. Process for the industrial preparation of (Z)-1-phenyl-1-diethylaminocarbonyl-2- aminomethylcyclopropane of formula I : see diagramm : EP0200638,P7,F2 characterized by the use of the following successive reaction steps : i) 1-phenyl-2-oxo-3-oxa(3: 1: 0) bicyclohexane of formula II : see diagramm : EP0200638,P8,F1 is opened by treatment with a phthalimide salt in an organic solvent ; ii) (Z)-1-phenyl-2-phthalimidomethylcyclopropane-carboxylic acid of formula III thus obtained see diagramm : EP0200638,P8,F2 is treated with an acid chloride, and then the acid chloride thus formed is amidified by condensation with diethylamine in an organic solvent ; and iii) (Z)-1-phenyl-1-diethylaminocarbonyl-2- phthalimidomethylcyclopropane of formula IV thus obtained : see diagramm : EP0200638,P8,F3 is then treated with an alkylamine or a primary hydroxyalkylamine by itself or in the presence of a solvent to obtain, after hydrochlorination, the compound of abovementioned formula I.</p> |
