1,4-Dioxane → 4-Hydroxymethyl-2,6-di-t-butylpyridine

Participants

Reaction Steps

A heterogeneous solution of 4-bromomethyl-2,6-di-t-butylpyridine (Compound A, 1.743 g, 82% purity) in 20 ml of 12% NaOH in water and 10 ml of 1,4-dioxane was refluxed for 12 hours. The solution spontaneously separated into two layers as it cooled to room temperature. The upper layer was separated and ethyl acetate was added. This organic layer was then washed with brine, water and dried over MgSO4. The desired product was purified by column chromatography (ethyl acetate/hexane 1/9) to give a white solid. 1H NMR δ7.09 (s, 2H), 4.67 (d, J=4.4 Hz, 2H), 2.3 (b, 1H), 1.36 (s, 18H).
