実験手順
Acetic anhydride (3.14 g, 30.76 mmol) was added to a solution of (+)-3-methoxy-morphinan hydrochloride (1.5 g, 5.1 mmol) in TI-IF (30 ml) and triethylamine (8.7 g, 85.98 mmol) in the presence of nitrogen. The resulting solution was heated at 60° C. for 15 hr. The reaction mixture was cooled to room temperature and evaporated under vacuum. The residue was dissolved in methylene chloride (50 ml), washed with water (40 ml×2) and dried (MgSO4). Evaporation of the dried solution gave a tan viscous oil (1.25 g, 81% yield); ms (ESI+): m/z 300 (M+1).
