Dissolve 4-(2-benzyloxy-ethyl)-2,2,6,6-tetramethyl-morpholine (490 mg, 1.77 mmol) MeOH (40 mL). Add to a pressure vessel containing a slurry of 10% Pd/C (100 mg) in MeOH (20 mL). Pressurize with 45 psi hydrogen gas. Monitor the reaction by MS. After 48 h, add another portion of 10% Pd/C (100 mg) and re-pressurize to 45 psi hydrogen. Stir an additional 3 days. Filter the reaction mixture through Celite® eluting with MeOH. Concentrate to give the desired product in quantitative yield. MS (ES+) 188.3 (M+1)+.
