  • Preparation of 2-substituted pyridines
    Patent number: 6054583
    Abstract: This invention relates to a process for preparing 2-substituted pyridines via metal halogen exchange with sec-butyllithium on optionally substituted 2-bromo or 2-iodopyridines. The resulting lithopyridine intermediate is reacted with an electrophile to provide the desired 2-substituted pyridine. The substitution of sec-butyllithium for n-butyllithium in such a process results in an enhanced yield and purity of the desired 2-substituted pyridine.
