A mixture of 12.42 g of 2-cyanomethyl-3-hexadecyloxypropyl benzoate n3' and 15.5 ml (31.0 mM) of 2N aqueous sodium hydroxide in 60 ml of methanol and 100 ml of tetrahydrofuran is stirred at room temperature for 1 hour and solvents are evaporated. The product is isolated by ethyl acetate extraction. The ethyl acetate layer is washed with water, dried over anhydrous magnesium sulfate and evaporated. Purification by column silica gel chromatography using n-hexane-ethyl acetate (4:1) affords 6.430 g (67.8% yield) of the titled compound Vn1.
