Abstract
NEW MATERIAL:A dihydrobenzofuran derivative of formula I (R1 is group of formula II or III; R2 is lower alkyl).
EXAMPLE: 3-(2'-Hydroxyphenyl)-1-methyl-quinolin-2-one.
USE: Usable as an agricultural chemical, a medicine, etc. and useful as various synthetic raw materials utilizing the reactivity thereof.
PROCESS: A benzofurancarboxylic acid N-alkylanilide of formula IV is irradiated with light in a solvent, e.g. a hydrocarbon such as benzene, to give the compound of formula I. The concentration of the compound of formula IV in the solvent and other irradiation conditions may be suitably selected and determined.
