Reaction Steps

To 902 mg (1.827 mmol) of 1,5-anhydro-3-{[(1R,3S)-3-{[(1S,4S)-5-(tert-butoxycarbonyl)-2,5-diazabicyclo[2.2.1]hept-2-yl]carbonyl}-3-(1-hydroxycyclobutyl)cyclopentyl]amino}-2,3-dideoxy-4-O-methyl-D-erythro-pentitol was added 10 mL of 4 M HCl in dioxane, and a few drops of methanol sufficient to give a clear solution. The solution was stirred at ambient temperature for 45 minutes, then concentrated under reduced pressure to give 973 mg of the intermediate salt as a foam. 1H NMR (400 MHz, MeOD) δ ppm 1.57-1.70 (m, 1H) 1.73-1.93 (m, 4H) 1.93-2.10 (m, 4H) 2.14-2.28 (m, 2H) 2.29-2.44 (m, 3H) 2.46-2.59 (m, 2H) 3.35-3.77 (m, 12H) 3.98 (dd, J=11.6, 4.4 Hz, 1H) 4.26 (d, J=13.3 Hz, 1H) 4.45 (s, 1H) 5.21 (br. s., 1H).
