Procedure
Under nitrogen, diethyl azodicarboxylate (0.19 ml, 1.2 mmol) was added dropwise to a suspension of 4-(4-fluoro-2-methylindol-5-yloxy)-7-hydroxy-6-methoxycinnoline (0.2 g, 0.6 mmol), (prepared as described in Example 4), in DMF (4 ml) containing triphenylphosphine (0.31 g, 1.2 mmol) and 3-(4-acetylpiperazin-1-yl)propan-1-ol (0.15 g, 0.9 mmol). After stirring for 2 hours at ambient temperature, the volatiles were removed under vacuum. The residue was purified by column chromatography eluting with methylene chloride, followed by ethyl acetate/methylene chloride (1/1) followed by methanol/ethyl acetate/methylene chloride (1/4/5) followed by methanol/methylene chloride (1/9). The fractions containing the expected product were combined and evaporated to give 7-(3-(4-acetylpiperazin-1-yl)propoxy)-4-(4-fluoro-2-methylindol-5-yloxy)-6-methoxycinnoline (0.11 g, 37%).
