Reaction Steps

A mixture of 0.29 g (0.46 mmol) of (3R,3aS,6aR)hexahydrofuro[2,3-b]furan-3-yl N-[(1S,2R)-1-benzyl-3-((4-cyano-2,2-dimethylbutyl)[3-(methylamino)phenyl]sulfonylamino)-2-hydroxypropyl]carbamate and approximately 50 mg of Raney nickel (washed with water and MeOH) in 60 mL of 2M NH3/MeOH was subjected to hydrogenation at 45 psi. After 1.5 hours the reaction vessel was purged with nitrogen, catalyst removed by filtration through celite and the filtrate concentrated in vacuo. The residue was subjected to flash chromatography (SiO2, 9:1 CH2Cl2/2M NH3 in MeOH) to afford 0.22 g (76%) of the desired amine as a white foam. NMR (CDCl3): 7.39-7.19 (m, 6H), 7.10 (d, 1H), 7.04-6.92 (m, 2H), 6.81 (dd, 1H), 5.63 (d, 1H), 5.05 (q, 1H), 4.16 (br s, 1H), 4.09-3.80 (m, 4H), 3.70 (m, 2H), 3.31 (m, 2H), 3.21-3.00 (m, 3H), 2.99-2.58 (m, 5H), 2.90 (s, 3H), 2.57-2.10 (br, 2H), 1.82-1.07 (m, 6H), 1.04 (s, 3H), 0.92 (s, 3H). MS(ESI): 619(M+H).
