Abstract:The title compound 1 is an useful intermediate of isoxazolyl anti-microbial agents.It could be synthesized in several steps.Firstly,condensation of 3,4-Difluorobenzaldehyde and hydroxylamine hydrochloride followed by chlorination with NCS gave chlorinated 3,4-difluorobenzoxime 3.Secondly,reaction of allylamine with acetyl chloride gave acetyl allylamine 4.Finally,title compound 1 was obtained from 3 and 4 in an overal yield of 30.2%(based on 3,4-difluorobenzaldehyde)with a purity of 99.1%(HPLC).
Keywords:5-(acetamidomethyl)-3-[3-fluoro-4-(1-piperazinyl)phenyl]isoxazoline  3  4-difluorobenzaldehyde  antimicrobial agent
