Reaction Conditions:
with pyridine hydrochloride
Steps:
36 5-t-Butylpyrogallol
EXAMPLE 36 5-t-Butylpyrogallol 2,6-Dimethoxy-4-t-butylphenol (16.5 g, 0.08 mole) and pyridine hydrochloride (60 g) were heated at 200°-210° C. for 2 hours. The mixture was then added to iced dilute hydrochloric acid and the aqueous solution extracted twice with petroleum ether (b.p. 40°-60° C.) to remove any unchanged starter. The aqueous phase was saturated with salt and extracted three times with ether. Drying and running down gave 12.5 g title product (88%) m.p. 137°-9° C.
