Procedure

t-Butyl 3-(6-hydroxymethylpyridin-2-yl)-trans-acrylate (trans form) (16.86 g) was dissolved in 200 mL of ethanol, and 0.5 g of platinum dioxide was added to the solution, and then the mixture was stirred under atmospheric hydrogen pressure at room temperature for 5 hours. After that, the catalyst was filtrated off, another platinum dioxide (0.5 g) was added, and then the mixture was stirred under atmospheric hydrogen pressure at room temperature for 6 hours. The catalyst was filtrated off from the reaction mixture, and the solvent was removed under reduced pressure to give 16.13 g of t-butyl 3-(6-hydroxymethylpyridin-2-yl)propionate as a light yellow oil.
