反応手順

A solution of 4-(3-hydroxy-prop-1-ynyl)-benzoic acid methyl ester (12.65 g) in EtOAc (75 mL) and MeOH (75 mL) was hydrogenated at 50 psi on a Parr shaker in the presence of 10% palladium on carbon (2 g) for 24 h. The catalyst was removed by filtration through Celite® and the filtrate was concentrated. The reaction was repeated by adding 10% palladium on carbon (2 g) and hydrogenating on a Parr shaker for 24 h. After filtering through Celite®, the solution was concentrated in vacuo to provide 4-(3-hydroxy-propyl)-benzoic acid methyl ester (11.98 g).
