To a solution of trans N-benzyl-2-methoxy-N-[(2-methylcyclopropyl)methyl]ethanamine hydrochloride (16 g, 59.3 mmol) in EtOH (400 mL), degassed with Argon, was added Pd(OH)2 (830 mg, 20%), and the mixture was stirred under 1 atm H2, at room temperature for 4 h. The reaction mixture was purged with N2, filtered on celite, under N2, concentrated in vacuo, and dried under vacuum over P2O5 to give trans (2-methoxyethyl)[(2-methylcyclopropyl)methyl]amine hydrochloride as a white foam. 1H NMR (400 MHz, CDCl3) δ 9.46 (bs, 2H), 3.84 (t, J=5.1 Hz, 2H), 3.40 (s, 3H), 3.23 (bt, J=5.1 Hz, 2H), 3.08-2.88 (m, 2H), 1.09 (d, J=6.1 Hz, 3H), 1.02-0.91 (m, 1H), 0.86-0.78 (m, 1H), 0.65-0.57 (m, 1H), 0.50-0.42 (m, 1H).
