実験手順

A mixture of bis(1,1-dimethylethyl) {3-{1-[(2,5-difluorophenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7-[2-({[(phenylmethyl)oxy]carbonyl}amino)ethyl]furo[3,2-c]pyridin-4-yl}imidodicarbonate (149 mg, 0.190 mmol) and 4.0 M HCl in dioxane (2.0 mL, 8.00 mmol) was stirred at room temperature under Nitrogen for 4 hr. The crude reaction mixture was then concentrated in vacuo and azeotroped once with acetonitrile. The residue was taken up in DCM and passed through a PL-HCO3 MP-resin cartridge, rinsing with more DCM. The filtrate was then concentrated in vacuo to give the free base of phenylmethyl[2-(4-amino-3-{1-[(2,5-difluorophenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}furo[3,2-c]pyridin-7-yl)ethyl]carbamate (105 mg, 0.162 mmol, 85% yield) as an off-white foam (purity estimated at 90%). LC/MS (ES) m/z=583.6 [M+H]+. 1H NMR (400 MHz, DMSO-d6) d 2.86 (t, J=7.07 Hz, 2H), 3.22-3.34 (m, 4H), 3.96 (s, 2H), 4.31 (t, J=8.34 Hz, 2H), 5.02 (s, 2H), 5.38 (s, 2H), 7.14-7.44 (m, 12H), 7.68 (s, 1H), 7.93 (s, 1H), 8.12 (d, J=8.34 Hz, 1H).
