Reaction Steps

By a method similar to Production Example 108, step 4, [4-(2-hydroxyethyl)benzyl](triphenyl)phosphonium bromide (2.866 g, 6.004 mmol) and tert-butyl 4-(6-formylpyridin-3-yl)piperazine-1-carboxylate (1.458 g, 5.003 mmol) were condensed to give tert-butyl 4-(6-{2-[4-(2-hydroxyethyl)phenyl]vinyl}pyridin-3-yl)piperazine-1-carboxylate (5.684 g, quantitatively) as a colorless oil.
