Preparation Process: To prepare **8-linalyl acetate**, dissolve linalool (1.0 equiv) in anhydrous dichloromethane under nitrogen. Add acetic anhydride (1.2 equiv) and a catalytic amount of 4-dimethylaminopyridine (DMAP, 0.1 equiv). Stir the mixture at room temperature for 4–6 hours, monitoring by TLC. Quench the reaction with saturated NaHCO₃ solution, extract with DCM, and wash the organic layer with water and brine. Dry over anhydrous Na₂SO₄, filter, and concentrate under reduced pressure. Purify the crude product by column chromatography (silica gel, hexane/ethyl acetate) to obtain pure 8-linalyl acetate.
