A solution of 55 mg (0.087 mmol) of (3R,3aS,6aR)hexahydrofuro[2,3-b]furan-3-yl N-[(1S,2R)-3-((6-amino-2,2-dimethylhexyl)[3-(methylamino)phenyl]sulfonylamino)-1-benzyl-2-hydroxypropyl]carbamate and 17.0 μL (0.091 mmol) of N,N-diisopropylethylamine in 4 mL of anhydrous THF at 0° C. was treated with 7.0 μL (0.091 mmol) of methyl chloroformate. The solution was allowed to warm to RT with stirring. After 18 hours the solution was concentrated in vacuo and the residue was subjected to flash chromatography (SiO2, 95:5 CH2Cl2/2M NH3 in MeOH) to afford 55 mg (92%) of the desired compound as a white foam. H1-NMR (CDCl3): 7.34-7.12 (m, 6H), 7.02 (d, 1H), 6.94 (s, 1H), 6.78 (d, 1H), 5.60 (d, 1H), 5.17 (d, 1H), 5.02-4.70 (m, 2H), 4.14 (s, 1H), 4.02 (m, 1H), 3.89 (dd, 1H), 3.79 (m, 2H), 3.72-3.55 (m, 5H), 3.28-2.91 (m, 6H), 2.83 (s, 3H), 2.89-2.64 (m, 3H), 1.65-1.18 (m, 8H), 0.91 (s, 3H), 0.88 (s, 3H). MS(ESI): 691 (M+H).
