Procedure

N-[5-(3-Amino-4-chlorophenoxy)[1,3]thiazolo[5,4-b]pyridin-2-yl]cyclopropanecarboxamide (200 mg, 0.554 mmol) produced in Example C118(ii), 2-chloro-3-(1-cyano-1-methylethoxy)benzoic acid (199 mg, 0.830 mmol) produced in Example C70(i) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (422 mg, 1.11 mmol) were suspended in pyridine (2 mL), and the suspension was stirred at 60° C. for 16 hr. After cooling to room temperature, ethyl acetate (100 mL) and water (80 mL) were added, and the mixture was partitioned. The organic layer was washed with saturated brine (50 mL), dried over anhydrous magnesium sulfate, and dried under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane=40/60→100/0) and basic silica gel column chromatography (ethyl acetate/methanol=100/0→90/10), and triturated with diisopropyl ether to give the title compound (78 mg, 24%) as white crystals.
