• Manufacturing Process

  7.7 g of dihydrocodeinone are heated with 40 ml of acetic anhydride for 2.5 hours under a reflux condenser, and the acetic anhydride and glacial acetic acid are then distilled off in vacuo. The oily residue is dissolved in water. In order to remove the last residues from the acetic anhydride it is extracted with ether. The new base is then precipitated with ammonia and crystallizes out immediately on addition of a small quantity of ether. The chemical analysis of the substance obtained corresponds to the values calculated for monoacetyl dihydrocodeinone.
