실험 절차

The mixture containing 2-(3-tert-butylphenylamino)benzo[d]thiazol-5-ol (1 eq), potassium bis(trimethylsilyl)amide (4 eq), and potassium carbonate (1.2 eq) in dimethylformamide was stirred at room temperature for 10 minutes. N-(4-chloropyridin-2-yl)-1-methylpiperidine-4-carboxamide (1.4 eq) was then added and mixture subjected to microwave at 220° C. for 20 minutes. Reaction partitioned between ethyl acetate and water. Organic layer separated, washed with brine, dried over sodium sulfate and concentrated to give crude product. Purification by HPLC to yield N-[4-({2-[(3-tert-butylphenyl)amino]-1,3-benzothiazol-5-yl}oxy)pyridin-2-yl]-1-methylpiperidine-4-carboxamide. HPLC=4.74 min; MS: MH+=516.
