合成路线1

Sulfonylation of methyl 3-methylanthranilate (I) with 4-methoxybenzenesulfonyl chloride (II) provided the sulfonamide (III). This was then N-alkylated with 3-picolyl chloride hydrochloride (IV) in the presence of K2CO3 to afford (V). Ester (V) hydrolysis with LiOH or NaOH provided carboxylic acid (VI), which was further activated as the corresponding acid chloride (VII) using oxalyl chloride in the presence of DMF. Coupling of acid chloride (VII) with hydroxylamine hydrochloride furnished the target hydroxamic acid, which was finally treated with HCl to produce the title hydrochloride salt.
