Procedure

A solution of 4-hydroxypiperidine (0.5 g, 4.95 mmol) and 7-(3-bromopropoxy)-4-(4-fluoro-2-methylindol-5-yloxy)-6-methoxycinnoline (0.3 g, 0.65 mmol) in DMF (4 ml) was stirred at 60° C. for 30 minutes. The volatiles were removed under vacuum and the residue was purified by column chromatography eluting with ethyl acetate/methylene chloride (1/1) followed by ethyl acetate/methanol/methylene chloride (4/1/5) followed by methylene chloride/methanol saturated with ammonia (9/1). The fractions containing the expected product were combined and evaporated to give 4-(4-fluoro-2-methylindol-5-yloxy)-7-(3-(4-hydroxypiperidin-1-yl)propoxy)-6-methoxycinnoline (25 mg, 8%).
