Procedure
3.5 g of methyl 3-(1-pyrrolidinyl)-2-(2,4-dichloro-5-fluorobenzoyl)acrylate are heated to boiling under reflux with 0.8 g of cyclopropylamine and 50 ml of toluene for one hour. The toluene is removed by distillation in vacuo, and the residue is recrystallized from acetonitrile. 2.5 g of methyl 3-cyclopropylamino-2-(2,4-dichloro-5-fluorobenzoyl)acrylate of melting point 150°-151° C. are obtained.
