Procedure

Aqueous sodium hydroxide (3.23 g, 80.0 mmol, dissolved in 28 mL of water) was added to an ice cold solution of 3,5-Dinitro-benzoic acid 4-isopropenyl-cyclohex-1-enylmethyl ester (14.0 g, 40.4 mmol) in methanol (140 mL) over a period of 0.25 h. The reaction mixture was allowed to warm to room temperature and then stirred for 3.0 h. The methanol was concentrated under vacuum and the resulting residue was suspended in water (60 mL) and extracted with ethyl acetate (2×100 mL). The organic layer was washed with water (2×100 mL) followed by brine (15%, 100 mL) and dried over sodium sulphate (30 g). The filtered organic layer was concentrated under vacuum to get pure (S)-perillyl alcohol (Weight: 5.84 g, Yield: 95% Purity: 99.4% by GC).
