A 100 ml of one neck round bottom flask equipped with a Dean Start trap, condensor and nitrogen inlet/outlet was charged with 20.8 g (0.20 moles) 3-hydroxybutyric acid, 63.3 g (0.40 moles) decyl alcohol, and 0.1 g sulfuric acid. The mixture was heated to 140° C. for 8 hours and water was collected as the reaction proceeded. The acid was neutralized by washing three times with 50 ml saturated sodium bicarbonate solution. The organic layer was collected and dried over magnesium sulfate. Excess decyl alcohol was removed by high vacuum distillation to yield 28.3 g (58% yield) of clear viscous colorless oil. According to GC the product is 89.4% pure.
