Water → 2,2-Dimethylmalonic acid mono-(2,2-dimethylpropyl)ester

참여 물질

반응 단계

To a solution of the obtained 2,2-dimethylmalonic acid t-butyl ester (2,2-dimethylpropyl)ester (12 g) in dichloromethane (100 mL), TFA (20 mL) was added, and the resulting mixture was stirred at room temperature for 3 hours. Ethyl acetate and water were added to the mixture. After shaking the resulting mixture, the organic layer was collected, sequentially washed with water and saturated aqueous sodium chloride solution, and dried over anhydrous magnesium sulfate. The desiccant was filtered off, and toluene was added to the filtrate obtained, after which the resulting mixture was concentrated under reduced pressure to obtain the captioned compound (8.7 g).
