Hydrochloric Acid → 2-(Piperidin-4-yloxy)isoindoline-1,3-dione hydrochloride

Participants

Reaction Steps

Hydrogen chloride in 1,4-dioxane (4 M, 7.0 ml) was added to the solution of tert-butyl 4-(1,3-dioxoisoindolin-2-yloxy)piperidine-1-carboxylate (692 mg, 2.00 mmol) in 1,4-dioxane (4 ml) and stirred for 1 hour. The precipitated material was collected, washed with n-hexane (2 ml×2) and dried under reduced pressure at 80° C. to give 2-(piperidin-4-yloxy)isoindoline-1,3-dione hydrochloride (533 mg, 94%).
