Participants

Reaction Steps

A mixture of 2-methoxy-5-(3-methyl-2-butenyl)hydroquinone (2.35 g) and acetic anhydride (4.6 g) in dry pyridine (20 ml) was stirred for 2 hours at ambient temperature. The mixture was poured into ice water (50 ml) and the separated oil was extracted twice with diethyl ether. The combined extracts were washed twice with diluted hydrochloric acid, dried, and concentrated in vacuo to give a white solid, which was recrystallized from n-hexane to yield 2-methoxy-5-(3-methyl-2-butenyl)hydroquinone diacetate as white crystals (2.89 g).
