摘要: A process for producing a benzoylacrylic acid derivative (formula 1) in high yield through a small number of steps and a simple purification step. The process comprises reacting 2,4,5-trifluoro-3-methyl-6-nitrobenzoyl chloride with a compound (formula 2) to yield an aminoacrylic acid derivative (formula 1) and then reacting the aminoacrylic acid derivative (formula 1) with an amine derivative represented by R2—NH2, wherein R2 is a cycloalkyl group or the like.
