合成路线1

该中间体在本合成路线中的序号：(V)

1,4-Diaminocyclohexane (I) is converted into the mono-carbamate (II) employing di-tert-butyl dicarbonate in cold THF. Subsequent reduction of carbamate (II) by means of LiAlH4 leads to the N-methyl amine (III). After blocking the primary amino group of (III) as the corresponding benzaldimine (IV), treatment with di-tert-butyl dicarbonate gives rise to the mono-protected diamine (V). (1,2)

合成路线2

该中间体在本合成路线中的序号：(V)

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)
