Procedure
To a solution of methyl 2-(4-(benzo[d]thiazol-2-ylamino)phenoxy)nicotinate (0.70 g, 1.84 mmol) in a mixed solvent of THF (6 mL) and water (2 mL) was added lithium hydroxide monohydrate (0.39 mg, 9.2 mmol). The reaction mixture was stirred at RT for 16 h. The reaction was quenched with aqueous 2N HCl to pH 5. The precipitate formed was collected by filtration, washed with water, dried to provide 2-(4-(benzo[d]thiazol-2-ylamino)-phenoxy)nicotinic acid as off-white solid. MS (ESI, pos. ion) m/z: 364.0 (M+1). IC50 (uM) +.
