8-acetyl-8-azabicyclo[3.2.1]octan-3-one

Conditions: temp:70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A suspension of nortropinone hydrochloride (1 g, 6.187 mmol) in acetic anhydride was stirred at 70° C. for 3 h. Water was added, the mixture was boiled for 30 min and cooled down to room temperature. CH2Cl2 and 1N aqueous NaOH was added until pH 9 was reached. The mixture was extracted 2 times with CH2Cl2, the combined organic layers were dried over Na2SO4, filtrated and the solution was evaporated to dryness to give 0.7 g of 8-Acetyl-8-aza-bicyclo[3.2.1]octan-3-one (4a). the mixture was boiled for 30 min cooled down to room temperature The mixture was extracted 2 times with CH2Cl2 the combined organic layers were dried over Na2SO4 filtrated the solution was evaporated to dryness
