実験手順

To a solution of N-[6-(3-aminophenoxy)-1,3-benzothiazol-2-yl]acetamide (160 mg, 0.534 mmol) produced in Example A40(x), 3-[(1,1-dimethylprop-2-yn-1-yl)oxy]benzoic acid (215 mg, 1.07 mmol) in pyridine (5 mL) was added O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (407 mg, 1.07 mmol) under ice-cooling, and the mixture was stirred at room temperature for 1 hr. The reaction mixture was poured into water (100 mL), and the mixture was extracted with ethyl acetate (100 mL). The organic layer was dried over anhydrous sodium sulfate, the insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate=80/20→0/100), and crystallized from ethyl acetate to give the title compound (181 mg, 70%) as colorless crystals.
