N-methyl-N-[((1S,2R)-1-phenyl-2-{[(phenylmethyl)oxy]methyl}cyclopropyl)methyl]benzenesulfonamide (1.57 g, 3.74 mmol), accessed via the method of preparation 6A, was combined with 10% palladium on activated carbon (0.35 g) in EtOAc and hydrogenated under 1 atm H2(g) for 4 h at ambient temperature. The catalyst was filtered off through celite and the filtrate concentrated to give the title product (1.17 g, 3.53 mmol, 95%) as a clear oil. 1H NMR (300 MHz, CDCl3) δ 7.68-7.18 (m, 10H), 4.07-4.03 (m, 1H), 3.72-3.66 (m, 1H), 3.55 (d, J=14.1 Hz, 1H), 3.25 (d, J=14.1 Hz, 1H), 2.36 (s, 3H), 1.59 (m, 1H), 1.18-1.15 (m, 1H), 0.79 (m, 1H). ES-LCMS m/z 354.3 (M+Na).
