Reaction Steps

In a 50-ml Erlenmeyer flask made of quartz, 0.5 g of (E) ethyl 3-(2-amino-5-chlorophenyl)-2-methyl-2-propenate was dissolved in 10 ml of ethanol; and, while being stirred, the mixture was irradiated with ultraviolet rays at 256 nm for 72 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.
