반응 단계
Sodium ethoxide was prepared from sodium metal (9.1 g) and freshly distilled absolute ethanol (250 ml). Diethyl malonate (63.5 g) was added to sodium ethoxide in ethanol, and the mixture was stirred at 60°-70° C. for 50 min. Isoamyl bromide (60 g) was added, and the reaction mixture was heated under reflux overnight. After the usual work-up, the resulting crude product was distilled under reduced pressure to give diethyl isoamylmalonate. Yield: 71.7 g (78%).
