tert-Butanol → Benzoic Acid

Participants

Reaction Steps

A mixture composed of 3.15 g of (E)-3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]benzenecarboxaldehyde, 1.44 g of potassium tert-butoxide and 100 ml of tert-butanol was heated to reflux for 2 hr while exposed to air. The mixture was then diluted with 100 ml of ice water. This mixture was then acidified with acetic acid and extracted with methylene chloride. The combined extracts were washed with water, brine, dried (MgSO4) and concentrated in vacuo to yield (E)-3-[2-(4-cyclobutyl)-2-thiazolyl)ethenyl]benzoic acid; m.p. 172°-175° C. from ethyl acetate.
