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). |
Key words:5-(acetamidomethyl)-3-[3-fluoro-4-(1-piperazinyl)phenyl]isoxazoline; 3,4-difluorobenzaldehyde;antimicrobial agent |
