Sulfonylation of methyl 5-bromo-3-methylanthranilate (I) with acid chloride (II) affords sulfonamide (III). Subsequent alkylation of the sulfonamide N of (III) with iodomethane and K2CO3 yields (IV). After protection of the phenolic hydroxyl group of (IV) as the silyl ether (V), benzylic halogenation with N-bromosuccinimide furnishes bromide (VI). Displacement of its benzylic bromide with 1-methylpiperazine (VII) occurs with concomitant desilylation to give (VIII). Mitsunobu coupling of phenol (VIII) with 2-butyn-1-ol (IX) leads to the propargyl ether (X). The methyl ester group of (X) is then hydrolyzed under alkaline conditions to furnish the carboxylic acid (XI).
