반응 단계
A suspension of 4-chloro-6-methoxy-7-[(2-methylthiazol-4-yl)methoxy]cinnoline (150 mg, 0.46 mmol) and 2-fluoro-5-hydroxy-4-methylaniline (78 mg, 0.56 mmol), (prepared as described for the starting material in Example 11), in 2-pentanol (3 ml) and a 5M solution of hydrogen chloride in isopropanol (105 μl) was heated at reflux for 90 minutes. The solid obtained was filtered off, washed with isopropanol followed by ether to give 4-(2-fluoro-5-hydroxy-4-methylanilino)-6-methoxy-7-[(2-methylthiazol-4-yl)methoxy]cinnoline hydrochloride as a pale yellow solid (190 mg, 82%).
