合成路线1
该中间体在本合成路线中的序号：(X)Suzuki coupling between 2-methoxy-5-formylphenylboronic acid (VI) and 4-bromobenzonitrile (VII) affords the biphenyl aldehyde (VIII). This is then reductively condensed with amine (V) in the presence of NaBH(OAc)3 to furnish (IX). Acylation of amine (IX) with 3-chlorobenzo[b]thiophene-2-carbonyl chloride (X) leads to amide (XI). The N-Boc protecting group of (XI) is finally removed with ethanolic HCl to provide the title compound. (1,2)
