Ethyl 3-(2-aminophenyl)-2-methyl-2-propenate → 3-methylquinolin-2(1H)-one

Participants

Reaction Steps

Into 10 ml of ethanol, 0.5 g of (E) ethyl 3-(2-aminophenyl)-2-methyl-2-propenate was dissolved; and, while being stirred, the mixture was irradiated with ultraviolet rays at 256 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.
