Versuchsvorschrift

The mixture containing 2-(3-isopropylphenylamino)benzo[d]thiazol-5-ol (1 eq), N-(4-chloropyridin-2-yl)acetamide (1.4 eq), potassium bis(trimethylsilyl)amide (4 eq) and potassium carbonate (1.2 eq) in dimethylformamide was subjected to the microwave at 200° C. for 15 minutes. The reaction was then partitioned between ethyl acetate and water. The organic layer was separated, washed with brine, dried over sodium sulfate and concentrated to give the crude product. Purification on HPLC to yield N-[4-({2-[(3-isopropylphenyl)amino]-1,3-benzothiazol-5-yl}oxy)pyridin-2-yl]acetamide. HPLC=4.87 min; MS: MH+=419.
