Process for the preparation of (1r,4r)-6'-fluoro-(N,N-dimethyl- and N-methyl)-4-phenyl-4',9'-dihydro-3'H-spiro[cyclohexane-1,1'-pyrano-[3,4,b]indol]-4-amine

摘要

A process for the preparation of (1r,4r)-6'-fluoro-N,N-dimethyl-4-phenyl-4',9'-dihydro-3'H-spiro[cyclohexane-1,1'-pyrano[3,4b]indol]-4-amine and (1r,4r)-6'-fluoro-N-methyl-4-phenyl-4',9'-dihydro-3'H-spiro[cyclohexane-1,1'-pyrano[3,4b]-indol]-4-amine or physiologically acceptable acid addition salts thereof.
