実験手順

A mixture of 1.43 g (2.26 mmol) of 3-{[(1R,3S)-3-[1-(acetyloxy)cyclobutyl]-3-{[(1S,4S)-5-(tert-butoxycarbonyl)-2,5-diazabicyclo[2.2.1]hept-2-yl]carbonyl}cyclopentyl](trifluoroacetyl)amino}-1,5-anhydro-2,3-dideoxy-4-O-methyl-D-erythro-pentitol and 1.60 g (11.6 mmol) of powdered potassium carbonate in 8 mL of methanol was stirred at ambient temperature for 18 h, then partitioned between dichloromethane and brine, with sufficient water to dissolve solids. The organic phase was dried (Na2SO4) and concentrated under reduced pressure. Flash chromatography of the residue on silica using acetate to provide 1.33 g (100%) of the title compound as a white foam. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.34-1.62 (m, 10H) 1.66-2.93 (m, 15H) 3.20-3.63 (m, 8H) 3.66-4.03 (m, 3H) 4.06-4.24 (m, 3H) 4.25-4.65 (m, 2H) 4.68-5.29 (m, 1H). TLC Rf 0.33 (EtOAc). LC-MS ES+ 590.3
