合成路线1
该中间体在本合成路线中的序号：(V)The reductocondensation of N-Boc-piperidin-4-one (I) with 3,4-dichloroaniline (II) by means of NaHB(OAc)3 in dichloroethane gives the secondary amine (III), which is acylated with chloroacetyl chloride (IV) by means of K2CO3 in dichloromethane to yield the chloroacetamide (V). The reaction of (V) with 3,5-dimethylphenol (VI) by means of Cs2CO3 in acetonitrile affords the aryl ether (VII), which is finally Boc deprotected with TFA in dichloromethane to provide the title trisubstituted acetamide.
