Into 30 ml of ethyl alcohol, 0.5 g of 3-(2-amino-4,5-dimethoxyphenyl)-2-methyl-2-propenoic acid ethyl ester was dissolved. This solution was irradiated with ultraviolet rays at 365 nm for about 20 hours, and the precipitated crystal was filtered out. This crystal was recrystallized from ethanol, whereby 0.38 g of the aimed compound was obtained (yield: 92%).
