合成路线1
该中间体在本合成路线中的序号：(XIV)N-alkylation of (S)-3-(benzyloxycarbonylamino)-2-pyrrolidinone (XIII) with propargyl bromide produced (XIV). Palladium-mediated coupling (XIV) with iodopyridine (X) gave adduct (XV), which was cyclized to the pyrrolopyridine (XVI) by means of DBU. The benzyloxycarbonyl protecting group of (XVI) was removed by transfer catalytic hydrogenolysis with formic acid, and the deprotected amine (XVII) was then condensed with sulfonyl chloride (VII) to furnish sulfonamide (XII). Deprotection of the Boc group of (XII) as above gave rise to the title compound.
