Reaction Steps

1,1-dimethylethyl [2-((1R,2R)-1-phenyl-2-{[(phenylmethyl)oxy]methyl}cyclopropyl)ethyl]carbamate (5.9 g, 15.46 mmol), accessed via the method of Preparation 24B was combined with 10% palladium on activated carbon (600 mg) in 100 mL ethyl alcohol and hydrogenated under 1 atm H2(g) for 3 h at ambient temperature. The catalyst was filtered off through celite and the filtrate concentrated to give the title compound (4.1 g, 14.07 mmol, 91%) as a colorless oil. 1H NMR (400 MHz, DMSO-d6) δ 7.27-7.12 (m, 5H), 6.59-6.56 (m, 1H), 4.31-4.29 (m, 1H), 3.00-2.94 (m, 1H), 2.87-2.66 (m, 3H), 1.88-1.82 (m, 1H), 1.32-1.25 (m, 10H), 1.11-1.05 (m, 1H), 0.76-0.73 (m, 1H), 0.65-0.63 (m, 1H). ES-LCMS m/z 314.1 (M+Na).
