合成路线1
该中间体在本合成路线中的序号：(III)Treatment of ethyl acrylate (I) with N-benzylmethylamine (II) affords aminopropionate derivative (III), which is then subjected to Grignard reaction with 3-bromoflurobenzene (IV) by means of Mg and catalytic iodine in refluxing THF and crystallized as a hydrochloride salt by treatment with HCl to provide propylamino derivative (V). Alcohol (V) is converted into allylamine (VI) by elimination induced by heating with HCl/HOAc, and finally the target product is obtained by hydrogenation of (VI) catalyzed by Pd(OH)2/C in EtOH.
