| Abstract
| - 2-Bromo-5-pyridylboronic acid 2a, 2-chloro-5-pyridylboronic acid 2b, 2-methoxy-5-pyridylboronic acid 2c,and 5-chloro-2-methoxy-4-pyridylboronic acid 4 have beensynthesized and shown to undergo palladium-catalyzedcross-coupling reactions with heteroaryl bromides to yieldnovel heteroarylpyridine derivatives. The X-ray crystalstructures of 2a and 2b have been obtained.
