Reaction Steps
A solution of 4,6-dimethyl-7-hydroxynonan-3-one (IVa, 10 g, 53.8 mmoles) in acetic anhydride (13.8 g, 135 mmoles) and pyridine (12.8 g, 162 mmoles) was set stirring under a nitrogen atmosphere. After stirring for 20 hours at room temperature, most of the acetic anhydride and pyridine were removed at reduced pressure to leave a clear oil (11 g crude weight). The crude product was then distilled at 60° C. and 0.16 mm to give a 68% yield of 4,6-dimethyl-7-acetoxynonan-3-one (8.4 g, 36.8 mmoles).
