Pyridoxol Hydrochloride

Fluorination of hydroxyamines is demonstrated by the conversion of 4,5-bis(hy-droxymethyl)-2-methylpyridin-3-ol hydrochloride (pyridoxol hydrochloride) into 4,5-bis-(fluoromethyl)-2-mcthylpyridin-3-ol hydrochloride (l).40... 

Pyridoxol hydrochloride (1.025 g. 5 mmol) was dissolved in anhyd liquid HF (30 inL) at — 78 C. The HF was evaporated to remove HCI and the residue redissolved in liquid HF (30 mL). Liquid SF4 (2mL. 35 mmol) was added and the solution allowed to remain at — 78 C overnight. The HF was then evaporated and the residue applied to a 100-mL column of Dowex 50X4 (acid form). The column was washed free of fluoride ion with H20 and eluted with 2.5 M HCI. The UV positive fractions were concentrated and the solid residue recrystallized (EtOH) yield 550 mg (52%) mp 142-143 C.

For the fortification of foods and for food supplements, synthetic pyridoxol hydrochloride (5-80) is used. Baby food, and in some countries white wheat flour, are the foods most often fortified.
