Reaction Steps
(S)-1-Methyl-2-pyridinemethanol was reacted with triphenylphosphine, DEAD and 3-hydroxypyridine according to the procedure outlined in Example 1a The crude product was purified by flash chromatography (2×) using (10% MeOH/CHCl3) to remove the diethyl hydrazine dicarboxylate impurity and give a yellow oil in 31% yield.
