Patent ID: 7015333

Claim:
A method for preparing an imidazolyl compound corresponding to formula (I) wherein: R a and R b are each individually selected from the group consisting of (C 1 –C 6 )alkyl, (C 1 –C 6 )alkoxyalkyl, and optionally substituted aryl and heteroaryl; or R a and R b together form a further homocyclic or heterocyclic system comprising one or more rings; R a′ and R b′ are each hydrogen or together form a carbon-carbon double bond, said carbon-carbon double bond optionally being part of an aromatic system; R c is hydrogen, (C 1 –C 6 )alkyl, (C 1 –C 6 )alkoxy, (C 1 –C 6 )alkoxyalkyl or halogen; R d is hydrogen or (C 1 –C 4 )alkyl; R e is hydrogen or (C 1 –C 4 )alkyl; m is 1 or 2; and R 1 is hydrogen or (C 1 –C 4 )alkyl; or an acid addition salt thereof; said method comprising: a) reacting a compound corresponding to formula (II) wherein R a , R a′ , R b and R b′ have the meanings defined above; with a compound corresponding to formula (III) wherein: R is a hydrogen, a (C 1 –C 4 )alkyl optionally substituted with a hydroxyl group, or an optionally substituted aryl group, and R′, R″, R′″ and R″″ are each individually a hydrogen or a (C 1 –C 4 )alkyl group; and then b) reacting a product of step a) with a compound corresponding to formula (IV) wherein R 1 , R d and R e have the meanings defined above; and c) optionally reacting a product of step b) with an acid to obtain an acid addition salt.
