Reaction Steps

According to the similar manner described in Example 97-B (i) and (ii), the title compound (237 mg, 78%) has been obtained as a brown solid by the Suzuki coupling reaction followed by standard ester hydrolysis reaction using methyl 2-(2-methylpyrazolo[1,5-a]pyridin-3-yl)-4-{[(trifluoromethyl)sulfonyl]oxy}-1,3-thiazole-5-carboxylate (339 mg, 0.805 mmol) obtained in Example 13-B (ii) and 2,3-difluoro-6-methoxyphenylboronic acid (303 mg, 1.61 mmol). The pure title compound has been obtained by washing with EtOAc (10 mL).
