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), triphenylphosphine (0.31 g, 1.2 mmol) and 3-(4-methylsulfonylpiperazin-1-yl)propan-1-ol (0.2 g, 0.9 mmol) in DMF (4 ml). The mixture was stirred for 2 hours at ambient temperature. Methylene chloride was added and the mixture was poured onto silica and eluted with ethyl acetate/methylene chloride (1/1) followed by methanol/ethyl acetate/methylene chloride (1/4/4) followed by methanol/methylene chloride (1/9). The fractions containing the expected product were combined and evaporated. The residue was triturated with diethyl ether and filtered. The solid was washed with ether and dried under vacuum to give 4-(4-fluoro-2-methylindol-5-yl)oxy-6-methoxy-7-(3-(4-methylsulfonylpiperazin-1-yl)propoxy)cinnoline (90 mg, 28%).
