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).
