合成路线1
该中间体在本合成路线中的序号：(IX)3,5-Dimethylphenol (I) was alkylated with ethyl 4-bromobutyrate (II) to provide the (dimethylphenoxy)butyrate ester (III), which was hydrolyzed under basic conditions to yield acid (IV). This was sulfonated with chlorosulfonic acid, and the resultant sulfonyl chloride (V) was condensed with Boc-diaminopropanoic acid (VI) to afford sulfonamide (VII). Coupling of (VII) with mono-benzyloxycarbonyl ethylenediamine (VIII) furnished amide (IX). Then, acid cleavage of the Boc protecting group of (IX) provided amine (X).
