Procedure
The above amide (10.0 g, 29.4 mmol) dissolved in 75 mL of absolute ethanol. To this solution was added 3 g of 10% Pd/C. The mixture was hydrogenated at 1 arm for 5 hours The catalyst was then removed by passing the reaction through a pad of celite. Concentration of the filtrate provided crude N-(4-hydroxybenzamido)-L-proline methyl ester that was purified by chromatography (SiO2, 30% ethyl acetate/hexanes) to provide 6.3 g (86%) as a white solid.
