Pyridoxal hydrochloride → Pyridoxal

Participants

Reaction Steps

1.016 g (5 mmol) of pyridoxal hydrochloride (Aldrich) was placed in an Erlenmeyer and a solution of 0.456 g sodium bicarbonate (5.4 mmol) in 5 mL water was added. The resulting solution was set aside for some time and crystals precipitated. The thus precipitated crystals were collected by filtration, washed with cold water and dried to afford 0.68 g of the pyridoxal free base (80% yield).
