Abstract
The reaction of 2-(pyridin-2-yl)benzoxazole and 2-(pyridin-2-yl)benzothiazole with methyl iodide forms the corresponding pyridinium salts. In the case of 2-(pyridin-2-yl)benzimidazole, the imidazole ring is quaternized first, and only then the pyridine ring. The catalytic hydrogenation of 2-(benzoxazol-2-yl)-1-methylpyridinium salts gives 2-(1-methylpiperidin-2-yl)benzoxazole.
