Reaction Steps

10% Pd/C (0.10 g) is added to a solution of (2R,6R,11R)-trifluoro-methanesulfonic acid 3-[(S)-2,3-dihydro-benzo[1,4]dioxine-2-carbonyl]-6,11-dimethyl-1,2,3,4,5,6-hexahydro-2,6-methano-benzo[d]azocin-8-yl ester (0.50 g) in methanol (15 mL) and ethyl acetate (25 mL). The resulting mixture is shaken under hydrogen atmosphere (50 psi) at room temperature overnight. Then, the catalyst is separated by filtration and the filtrate is concentrated under reduced pressure. The residue is purified by HPLC on reversed phase (MeCN/H2O) to give the product as a colorless gum-like solid.
