実験手順
A solution of 4-chloro-6-methoxy-7-(4-pyridylmethoxy)cinnoline hydrochloride (268 mg, 0.71 mmol), (prepared as described for the starting material in Example 10), and 2-fluoro-5-hydroxy-4-methylaniline, (109 mg, 0.77 mmol), (prepared as described for the starting material in Example 11), in 2-pentanol (6 ml) was heated at reflux for 4 hours. After dilution with isopropanol the solid was filtered off, washed with isopropanol followed by ether to give 4-(2-fluoro-5-hydroxy-4-methylanilino)-6-methoxy-7-(4-pyridylmethoxy)cinnoline hydrochloride (92 mg, 29%).
