Abstract:
This invention relates to a process for preparing (±)-2-exo-(2-Methylbenzyloxy)-1-methyl-4-isopropyl-7-oxabicyclo[2.2.1]heptane of the formula (I) any of its individual enantiomers or any non-racemic mixture thereof, comprising the steps of (a) reacting (±)-2-exo-hydroxy-1-methyl-4-isopropyl-7-oxabicyclo[2.2.1]heptane of the formula (II) any of its individual enantiomers or any non-racemic mixture thereof with a 2-Methylbenzyl compound of the formula (III) wherein X is a leaving group in the presence of at least one base capable of forming water or a C1-C4 alkyl alcohol under the reaction conditions, and at least one inert organic solvent, and (b) simultaneously removing water, the C1-C4 alkyl alcohol or any mixture thereof from the reaction mixture.
