Procedure

Pd(OH)2 (15.0 mg, 10% on carbon) was added to a solution of (2R,3R)-4-benzyl-3-ethyl-2-methylmorpholine (110 mg, 0.50 mmol) in MeOH (10 mL) under N2. Hydrogen was bubbled through the reaction mixture for one minute and then the reaction was stirred at rt under hydrogen (1 atm) for 2 hours. Then, N2 was bubbled through the reaction for 1 minute. A solution of HCl (3M, 3 mL, 9 mmol) in methanol was added. The reaction mixture was stirred at room temperature for 30 minutes and concentrated in vacuo to afford (2R,3R)-3-ethyl-2-methylmorpholine hydrochloride. 1H NMR (300 MHz, DMSO-d6) δ 9.45-9.34 (br s, 1H), 3.84-3.91 (m, 1H), 3.68-3.78 (m, 1H), 3.53-3.61 (m, 1H), 3.08-3.21 (m, 1H), 2.93-3.01 (m, 1H), 2.70-2.85 (m, 1H), 1.45-1.81 (m, 2H), 1.13 (d, J=6.3 Hz, 3H), 0.90-1.05 (m, 3H).
