Process for producing (Z)-1-phenyl-1-(N,N-diethylamino-carbonyl)-2-phthalimidomethylcyclopropane

摘要

The present invention provides a process for producing (Z)-1-phenyl-1-(N,N-diethylaminocarbonyl)-2-phthalimidometh ylcyclopropane, which includes reacting (Z)-1-phenyl-1-(N,N-diethylaminocarbonyl)-2-hydroxymethylcy clopropane with an orthoester and a brønsted acid, and reacting the reaction product with a phthalimidating agent; and a process for producing (Z)-1-phenyl-1-(N,N-diethylaminocarbonyl)-2-aminomethylcycl opropane hydrochloride through the above process.
