合成路线1
该中间体在本合成路线中的序号:(XIII)Acid (XI) was converted to the methyl ester (XII) by alkylation with iodomethane in the presence of Cs2CO3. After removal of the N-Cbz group of (XII) by catalytic hydrogenolysis, the resultant amine (XIII) was acylated by butanesulfonyl chloride (XIV) producing sulfonamide (XV). Saponification of the ester group of (XV) with LiOH gave acid (XVI). The N-Boc group of (XVI) was finally cleaved by treatment with HCl in EtOAc.
