Hydrochloric Acid → 5,5-Diphenyl-2-cyclopentenyl acetate

Participants

Reaction Steps

To a solution of 5,5-diphenyl-2-cyclopenten-1-ol (0.70 g) in pyridine (5 ml) were added acetic anhydride (0.84 ml) and catalytic amount of 4-dimethylaminopyridine at room temperature. After being stirred for 30 minutes, the pH of the reaction mixture was adjusted to 1.0 with diluted hydrochloric acid and extracted with ethyl acetate. The extract was washed with brine, dried over magnesium sulfate and evaporated in vacuo to give 5,5-diphenyl-2-cyclopentenyl acetate (0.82 g).
