実験手順

A solution of N-[5-(3-aminophenoxy)[1,3]thiazolo[5,4-b]pyridin-2-yl]cyclopropanecarboxamide (120 mg, 3.68 μmol) produced in Example C111(v), 2-chloro-3-(1-cyclopropyl)benzoic acid (90 mg, 405 μmol) produced in Example C62(ii) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (154 mg, 405 μmol) in pyridine (3 mL) was stirred at room temperature for 1 hr. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate solution (15 mL), and the mixture was extracted with ethyl acetate (20 mL, 5 mL). The combined organic layer was washed with saturated brine (5 mL), and 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=30/70→10/90), and fractions containing the object product were concentrated under reduced pressure. The obtained residue was recrystallized from tetrahydrofuran and ethanol to give the title compound (169 mg, 87%) as colorless crystals.
