Reaction Steps

To a solution of tert-butyl 4-(2-(piperidin-4-yloxy)benzo[d]thiazol-6-yl)piperidine-1-carboxylate (337 mg, 0.807 mmol) and 5-chloro-2-iodopyrimidine (213 mg, 0.888 mmol) in DMF (10 mL) was added potassium carbonate (335 mg, 2.421 mmol). The reaction mixture was stirred at 100° C. overnight. The reaction mixture was cooled to rt, diluted with water (30 mL), and extracted with EtOAc (3×10 mL). The combined organic layers were dried (Na2SO4), filtered, and concentrated. The residue was recrystallized from EtOAc to afford 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, 31% yield) as an off white solid. LCMS (m/z)=531 (M+H)+.
