  A process for producing a pivaloylacetic acid ester comprises reacting pivaloyl chloride with an acetoacetic acid ester of an alkyl group having 1 to 4 carbon atoms in the presence of at least one nitrogen-containing basic compound (a) selected from among pyridine compounds, N,N-dialkylanilines and imidazole compounds and from 0.01 to 0.5 mole equivalent, based on the pivaloyl chloride, of a magnesium compound (b) to thereby prepare a pivaloylacetoacetic acid ester and then alcholyzing or alkali-hydrolyzing the pivaloylacetoacetic acid ester to thereby give a pivaloylacetic acid ester having a high purity at a low cost.

  生产异丁酰乙酸酯的方法包括在至少选择自吡啶化合物、N,N-二烷基苯胺和咪唑化合物中的一种氮含基化合物（a）的存在下，将异丁酰氯与具有1至4个碳原子的烷基基团的乙酰乙酸酯反应，并加入相当于异丁酰氯的0.01至0.5摩尔当量的镁化合物（b），从而制备异丁酰乙酸乙酯，然后对异丁酰乙酸乙酯进行醇化或碱水解，从而以低成本获得高纯度的异丁酰乙酸酯。
