Abstract

Although this synthesis was structurally unanibiguous and proceeded in a satisfactory yield, a method based on 3-hydroxypyridine as a starting point now was desired for application to the substituted series, in which the only readily accessible starting material was the 3- hydroxy-4-methyl-5-phenylpyridine (VIII). ll Since 3-hydroxy-and-alkoxypyridines give predominantly exclusively 2-substituted products in typical aromatic substitution reactions ...
