Versuchsvorschrift

1 g (4.03 mmol) of the crude 2-(3,4-dimethyl-benzoyl)-3-methoxy-acrylic acid methyl ester 1a and 0.40 g (3.63 mmol) of 4-fluoroaniline were heated neat at 100° C. for 2 h. The reaction solution was cooled to room temperature and the crude product precipitated out of solution. The crude material was recrystallized from dichloromethane/hexane to yield 0.70 g of 2-(3,4-dimethyl-benzoyl)-3-(4-fluoro-phenylamino)-acrylic acid methyl ester 2g as brown crystalline solid.
