Reaction Steps

A solution of 6-hydroxy-2H-chromene-3-carboxylic acid (2.00 g, 10.4 mmol) in MeOH (100 mL) was degassed. To this solution was added Pd/C (5 wt %, 1.32 g). The reaction mixture was allowed to stir at rt under an atmosphere of hydrogen for 3 h and then filtered through Celite. Concentration of the filtrate gave 6-hydroxychromane-3-carboxylic acid (1.52 g, 75%). LCMS: ES− 193.1.
