Abstract
The reduction of 4-(benzoxazol-2-yl)- and 4-(benzothiazol-2-yl)-1-methylpyridinium iodides with sodium tetrahydroborate in an alkaline medium forms products of the dimerization of the corresponding 1,2-dihydropyridine derivatives. Under similar conditions, 4-(benzimidazol-2-yl)-1-methylpyridinium iodide gives a 1,2,5,6-tetrahydropyridine derivative.
