To a solution of tert-butyl 4-(2-((1-(5-chloropyrimidin-2-yl)piperidin-4-yl)oxy)benzo[d]thiazol-6-yl)piperidine-1-carboxylate (133 mg, 0.251 mmol) in CH2Cl2 (2.5 mL) was added TFA (0.2 mL, 2.5 mmol). The reaction mixture was stirred at rt for 3 h. The reaction mixture was diluted with CH2Cl2 (5 mL) and washed with aq. NaOH (1 N, 3 mL) and brine. The organic layer was dried (Na2SO4), filtered, and concentrated to afford 2-((1-(5-chloropyrimidin-2-yl)piperidin-4-yl)oxy)-6-(piperidin-4-yl)benzo[d]thiazole (102 mg, 0.237 mmol, 95% yield) as a pale yellow solid. LCMS (m/z)=430 (M+H)+.
