合成路线1
该中间体在本合成路线中的序号：(III)2-Phenyl-1,2,3-triazole-4-carboxylic acid (I) was converted to acid chloride, which was further treated with N-methoxy-N-methylamine to provide the corresponding Weinreb amide (II). Subsequent chlorosulfonylation of (II) gave rise to sulfonyl chloride (III), which was coupled with the known amine (IV), yielding sulfonamide (V). The Boc protecting group of (V) was then cleaved by means of trifluroacetic acid to afford (VI). Addition of Grignard reagent (VII) to the N-methoxyamide (VI) furnished ketone (VIII).
