The application describes a new method for producing 9-dichloromethylene-1,2,3,4-tetrahydro-1,4-methanonaphthalen-5-ylamine, which includes: a) a reaction of cyclopentadiene in the presence of a radical initiator and CXCl, where X is chlorine or bromine , to obtain a compound of formula (II), or aa) reaction of cyclopentadiene with CXCl, where X is chlorine, in the presence of a metal-containing catalyst to obtain a compound of formula (II), in which X is chlorine, b) the reaction of a compound of formula (II) with a base in the presence of a suitable solvent to obtain the compounds of formula (I II), c) and converting a compound of formula (III) in the presence of 1,2-dihydro-6-nitrobenzene to a compound of formula (IV) and d) hydrogenating a compound of formula (IV) in the presence of a metal-containing catalyst. |
