合成路线1
该中间体在本合成路线中的序号：(XV)Synthesis of intermediate (VI): Treatment of pyridone (X) with diphenyl phosphoryl azide (DPPA) followed by reaction with benzyl alcohol affords the protected derivative (XI), which then reacts with tert-butyl bromoacetate (XII) by means of Cs2CO3 to provide the acetate derivative (XIII). Hydrogenation of (XIII) over Pd/C allows Cbz removal, giving amine (XIV), which is then condensed with iodo derivative (XV) to furnish sulfonamide compound (XVI). Finally, hydrolysis of (XVI) is achieved by treatment with TFA to afford the target intermediate (VI).
