Reaktionsschritte

Using ethyl 2-(2-methylpyrazolo[1,5-a]pyridin-3-yl)-4-{[(trifluoromethyl)sulfonyl]oxy}-1,3-thiazole-5-carboxylate (500 mg, 1.2 mmol) produced in Example 15-B(i), (4-fluorophenyl)boronic acid (480 mg, 3.4 mmol), [1,1-bis(diphenylphosphino)ferrocene]palladium(II) dichloride dichloromethane complex (75 mg, 0.091 mmol), cesium carbonate (700 mg, 2.2 mmol), water (2 mL) and 1,2-dimethoxyethane (30 mL) as starting materials and in the same manner as in Example 13-B(iii), the title compound (310 mg, 73%) was obtained as a brown solid.
