Summary
-
1.
The condensation of ethylene oxide with 2-pyrrolidinone was studied. It was shown that 1-(2-hydroxyethyl) -2-pyrrolidinone was formed.
-
2.
In order to prove the structure of the (hydroxyethyl)pyrrolidinone it was converted into the (chloroethyl)pyrrolidinone by treatment with thionyl chloride. The yield of 1-(2-chloroethyl)-2-pyrrolidinone was about 90 %.[1].
