Concise and Efficient Synthesis of 4-Fluoro-1H-pyrrolo[2,3-b]pyridine
摘要:
[GRAPHICS]Two routes describing the preparation of 4-fluoro-1H-pyrrolo[2,3-b]pyridine (4a) from 1H-pyrrolo[2,3-b]pyridine N-oxide (1) are presented, Regioselective fluorination was achieved using either the Balz-Schiemann reaction or lithium-halogen exchange.

The present invention provides compounds of formula (I), (I) and pharmaceutically acceptable salts thereof.The formula I compounds inhibit the tyrosine kinase activity of growth factor receptors such as VEGFR-2 and FGFR-1, thereby making them useful as anti-cancer agents. The formula (I) compounds are also useful for the treatment of other diseases associated with signal transduction pathways operating through growth factor receptors.
