The method comprises: reacting diethyl malonate and strong alkaline solution at 70-80 deg.C for 10-30 min to obtain intermediate A, adding catalyst 0.5-1 wt.% of diethyl malonate, dropping halogenated ethyl carboxylate within 30-50 min, reacting at 70-80 deg. French chemist Victor Dessaignes reported the first synthesis of malonic acid in 1858; he made it by oxidatively decomposing four-carbon malic acid with potassium dichromate. Synthesis of Diethyl Succinate. That the alkylation stage can also produce dialkylated structures. The other prodrugs This process is very similar to the malonic ester synthesis except that the key reagent is ethyl acetoacetate rather than diethyl malonate. Diethyl succinate Msynth®plus. Butanedioic acid, bis(1-methylethyl) ester. In this work it was demonstrated that the use of excess of diethyl malonate led to decreasing yields of the cyclic derivative in favor of the tetraethyl ester of pentane -1, 1, Diisopropyl succinate # AI3-05513.
