Reaction Steps

In a 30-ml Erlenmeyer flask made of quartz, 200 mg of (E) ethyl 3-(2-amino-4-dimethylaminophenyl)-2-methyl-2-propenate were dissolved in ethanol; and, while being stirred, the mixture was irradiated with ultraviolet rays at 365 nm for 48 hours. The reaction liquid was concentrated under a reduced pressure, and the resulting crude crystal was recrystallized from ethanol, whereby the aimed compound was obtained (yield: 98%).
