Intermediates for making 1-(3-benzyloxyphenyl)-1,1-dimethylheptane

-

, (2008/06/13)

Process for making 1-(3-benzyloxyphenyl)-1,1-dimethylheptane, a valuable intermediate for the preparation of analgesic agents, which comprises benzylation of 3-hydroxyacetophenone to produce 3-benzyloxyacetophenone which is converted to 1-(3-benzyloxyphenyl)-1-methylheptan-1-ol via Grignard reaction with n-hexylmagnesium bromide; chlorination of said heptanol by reaction with hydrogen chloride followed by methylation of the thus-produced 1-(3-benzyloxyphenyl)-1-chloro-1-methylheptane with trimethylaluminum.
