PROCESS FOR PRODUCING FLUOROALKYLSULFONYLAMINOETHYL α-SUBSTITUTED-ACRYLATE

Title:

PROCESS FOR PRODUCING FLUOROALKYLSULFONYLAMINOETHYL α-SUBSTITUTED-ACRYLATE

Document Type and Number:

WIPO Patent Application WO/2010/074062

Kind Code:

A1

Abstract:

Aminoethanol is reacted with a fluoroalkylsulfonic anhydride to obtain a fluoroalkylsulfonylaminoethanol (first step: sulfonylamidation step). The fluoroalkylsulfonylaminoethanol is esterified with an α-substituted acrylate derivative to obtain a desired fluoroalkylsulfonylaminoethyl α-substituted-acrylate (second step: esterification step). Thus, the desired fluoroalkylsulfonylaminoethyl α-substituted-acrylate having a higher purity can be produced in higher yield with higher operating efficiency than in conventional techniques.
