The ethyl sec.-bulylmalonate was prepared from sec.-butyl bromide and malonic ester according to the general method described in Org. Syn. 4, ii. The yield of ester boiling at I24-I32V28 mm. was 80-81 per cent of the theoretical amount. The pdds of 3-methyl pentanoic add given in this procedure were obtained with this grade of ester.
