Abstract

PURPOSE: To obtain the title compound which is useful as an intermediate for α- amino acids such as serine, medicines, etc., in high yield, by hydrolyzing α-chloro- β-phthalimidopropionitrile.
CONSTITUTION: The title compound is obtained rapidly and easily by adding α-chloro-β-phthalimidopropionitrile to a mineral acid, pref. raising the temperature while stirring, and reacting at 50W150°C for 2W15hr. The reaction solution is subjected to thin-layer chromatography. The mineral acid is, e.g. hydrochloric acid, sulfuric acid, etc. Concentration of the mineral acid is selected appropriately in the range of 3W80wt%. Suitably in reaction operations, the amount of the mineral acid used is usually at least 2pts.wt. preferably at least 3pts.wt. to 1pt.wt. of α-chloro- β-phthalimidopropionitrile.
