Reaction Steps

A solution of NaNO2 (330 mg) in water (2 mL) is slowly added to a flask charged with a stir bar, 1-[(2R,6S)-8,9-diamino-6,11,11-trimethyl-1,2,5,6-tetrahydro-4H-2,6-methano-benzo[d]azocin-3-yl]-2,2,2-trifluoro-ethanone (650 mg), and acetic acid (15 mL) and chilled in an ice bath. The resulting mixture is stirred in the cooling bath for 2 h and at ambient temperature for 1 h. Then, the solution is poured into ice-cold water and the precipitate formed is separated by filtration and dried to afford the title compound that is used without further purification.
