Abstract: Crystals of the title compound, which is also commonly known as 6-O-acetylcodeine, C20H23NO4, were obtained by acetylation of codeine and subsequent crystallization of the product from ethyl acetate. The atoms of the benzene ring are nearly coplanar, whereas the five-memberedring is distorted. The ethanamine ring has a typical chair form conformation, while the cyclohexene ring is in a twisted boat form.
