Synthesis of N-methylspiro [1,2,3,4-tetrahydro-naphthalene-1,2'-pyrrolidine]

A pathway for synthesis of N-methylspiro [1,2,3,4-tetrahydro-naphthalene-1,2'- pyrrolidine] was developed. Formation of the imine compound from ${\alpha}$-tetralone and methylamine using titanium tetrachloride followed by ddition of allylmagnesium bromide gave (1-allyl-1,2,3,4-tetrahydro-naphthalen-1-yl)methylamine.
