Condensation of 4-fluorobenzenesulfonyl chloride (I) with anthranilic acid derivative (II) by means of pyridine yields sulfonamide derivative (III), which is then N-alkylated by reaction with benzyl bromide (IV) by means of NaH in DMF to furnish compound (V). Saponification of the methyl ester group of (V) by treatment with NaOH in refluxing MeOH affords carboxylic acid (VI) (1), which is then converted into compound (X) by condensation with hydroxy derivative (IX) by means of NaH in DMF. (In turn, compound (IX) can be obtained by coupling of 2-benzofurancarboxylic acid (VII) with ethanolamine (VIII) by means of HOBt/EDC and NMM in DMF. Finally, the target product is obtained by derivatization of the carboxylic acid moiety of (X) with hydroxylamine hydrochloride by means of HOBt/EDC and Et3N in DMF.
