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) and 3-(1-cyano-1-methylethoxy)benzoic acid (219 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 5 hr. The reaction mixture was poured into water (100 mL), and extracted with ethyl acetate (100 mL×2). The ethyl acetate layers were combined and dried over anhydrous sodium sulfate, and 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=100/0→0/100), and crystallized from ethyl acetate to give the title compound (141 mg, 54%) as colorless crystals.
