Reaction Steps

Anhydrous hydrogen bromide in glacial acetic acid (6 ml of 45% w/v solution) was added dropwise with stirring to a cooled (-15° C.) solution of thebaine (2 g) in chloroform (6 ml) over a period of 9 minutes. When the addition was complete the Drikold bath was removed and the temperature allowed to rise.
