Reaction Steps

8-chloro-6-methyl-5-phenyl-3,4-dihydro-pyrano[3,4-c]pyridine-1-on (120 mg, 0.438 mmol), palladium acetate (5.0 mg, 0.022 mmol) and sodium acetate (72 mg, 0.877 mmol) were suspended in 5 mL of anhydrous methanol and then stirred at room temperature for about 2 hours under the hydrogen atmosphere. The mixture was filtered and then concentrated under reduced pressure, added with 15 mL of a saturated solution of sodium hydrogen carbonate and then extracted twice with 20 mL of methylene chloride. The resulting organic layer was dried with anhydrous sodium sulfate, filtered and then concentrated. A silica gel column chromatography (2% MeOH/MC) was performed on the resulting residue and 101 mg (96%) of 6-methyl-5-phenyl-3,4-dihydro-pyrano[3,4-c]pyridine-1-on was obtained in white solid.
