66.64 g (0.4 mole) of cinnamoyl chloride and 300 g of methyl ketone (hereinafter referred to as MEK) were placed in a reaction vessel to be stirred by heating at 60° C. under a nitrogen current. 73.64 g (0.4 mole) of 3,5-dinitrophenol, 50 g of pyridine, and 500 g of MEK were added dropwise to the above reaction vessel using a dropping funnel. After that, reflux stirring was conducted for approximately 2 hours under a nitrogen current. After the completion of the reaction, the precipitate was separated by filtration. The filtrate was concentrated until crystals separated out and poured into methanol. 90 g of light yellow colored needle-like crystals (2, 4-dinitrophenyl cinnamate) were yielded.
