Versuchsvorschrift

A mixture of (5a)-17-(cyclopropylmethyl)-14-hydroxy-6-oxo-4,5-epoxymorphinan-3-yl trifluoromethanesulfonate [P1] (38.0 g, 80.3 mmol), zinc cyanide (18.85 g, 160.5 mmol), and tetrakis(triphenylphosphine)palladium(0) (8.5 g, 7.36 mmol) in DMF (500 mL—degassed with argon for 3 hours) was heated at 120° C. under argon for 3 hours. The reaction mixture was allowed to return to room temperature then diluted with ethyl acetate (IL) and passed through a pad of celite. The solution was washed with water (3×1 L) and the organic phase dried (MgSO4). Filtration and removal of the solvent under reduced pressure gave crude product that was triturated with methanol to give (5a)-17-(cyclopropylmethyl)-14-hydroxy-6-oxo-4,5-epoxymorphinan-3-carbonitrile [P2] (17.12 g, 61% yield); LC/MS (r.t. 12.7 minutes [5 to 95% B]), 351 (M+H)+.
