Reaction Steps

4 M aqueous NaOH solution (3.5 mL) is added to a solution of cis-4-[(2R,6S)-10-hydroxy-6,11,11-trimethyl-1,2,5,6-tetrahydro-4H-2,6-methano-benzo[d]azocine-3-carbonyl]-cyclohexane carboxylic acid methyl ester (1.2 g) in methanol (20 mL). The resulting solution is stirred at room temperature overnight. Then, 4 M hydrochloric acid is added, the resulting mixture is extratced with ethyl acetate, and the combined extratcs are dried (Na2SO4). After removal of the solvent, the residue is triturated with a mixture of acetonitrile and ether.
