실험 절차

To 500 ml of dry N,N-dimethylformamide, 17 g of 60% sodium hydride was added, and 48 g of methyl 2-hydroxyisobutyrate was added dropwise with stirring under ice-cooling, and stirred for 10 minutes. Then, 100 g of 9-bromo-1-nonene (purity: 63.4%) was added, and the mixture was stirred for 15 hours at room temperature. The reaction solution was poured into ice-cold water, extracted with ethyl acetate, washed with brine, dried over anhydrous magnesium sulfate and concentrated. The residue was distilled under reduced pressure to give 29.9 g of the objective compound as yellowish oil.
