摘要:
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.
