Participants

Reaction Steps

Malonic acid (40 g, 0.38 mol) and neopentyl alcohol (77.5 g, 0.88 mol) in 110 ml of toluene in the presence of 0.2 ml of concentrated sulfuric acid are refluxed for 3 hours in a reactor equipped with Dean-Stark apparatus. The water formed is removed azeotropically. The organic phase is washed 3 times with water and dried over sodium sulfate. After filtration and evaporation of the solvent under vacuum, 88 g (yield: 94%) of dineopentyl malonate are obtained in the form of a colorless oil and used without further purification in the next step.
