<p>Compounds of structure (2) are prepared by reaction of an arecoline analogue of structure (4) with an organometallic compound containing an X-substituted phenyl group, such as a compound of structure (3). Suitably the compound of structure (3) is a Grignard reagent, where M is magnesium and Y is a halogen atom, or M may be a Group II metal and Y is a halogen atom or a second X-substituted phenyl group. When structure (3) is a Grignard reagent, the reaction is carried out either in a suitable non-ether solvent, typically a hydrocarbon or a non-reactive chlorinated hydrocarbon, or in a mixture of such a solvent with diethyl ether. Compounds of structure (2) are important intermediates in the preparation of inter alia paroxetine.</p> |
