반응 단계
7.8 Parts of 4-chloro-4-chloromethyloxetan-2-one are dissolved in 200 parts of methanol containing 4.2 parts of anhydrous sodium bicarbonate. After stirring for 20 hours at room temperature, the solids are filtered off, the filtrate is evaporated and the residue distilled to give methyl-γ-chloroacetoacetate, b.p. 48°-50° C./0.8 mb.
