Kiran Singh

@ Sanchita Das Hi, you can synthesise it using alpha phellandrene and ruthenium trichloride in completely dry methanol under a nitrogen atmosphere. Mix them and stir the reaction mixture for 4-5 hours under reflux conditions. After that remove the solvent under vacuum and washed the brown colored ppt using ether so that extra phellandrene can be removed.

Thank you Kiran Singh for your help.
