To a stirred solution of tert-butyl 6-((3R,4R)-3-(tert-butoxycarbonylamino)tetrahydro-2H-pyran-4-ylamino)-7-fluoro-4-(isothiazol-5-yl)-3-oxo-1H-pyrrolo[3,4-c]pyridine-2(3H)-carboxylate (65.8 mg, 0.120 mmol) in MeOH (1.0 mL) was added 4N HCl/dioxane (1.0 mL, 4.00 mmol). The reaction mixture was heated to 60° C. for 1 hour and was subsequently concentrated in vacuo. The residue was triturated with EtOAc and filtered. The filter cake was washed with EtOAc to give a yellow solid, which was suspended into EtOH. The mixture was stirred at 80° C. for 30 minutes and allowed to cool to room temperature. The resulting precipitate was collected by filtration and washed with EtOH to give a hydrochloride salt of the title compound as an off-white solid (26.5 mg, 57%). 1H NMR (500 MHz, DMSO-d6) δ ppm 1.74-1.85 (m, 1H), 2.08-2.23 (m, 1H), 3.56-3.68 (m, 1H), 3.80 (d, J=11.23 Hz, 2H), 3.96-4.11 (m, 2H), 4.29-4.39 (m, 1H), 4.42-4.55 (m, 2H), 7.49 (d, J=5.37 Hz, 1H), 8.08 (br s, 3H), 8.63 (s, 1H), 8.71 (s, 1H), 8.96 (s, 1H). ESI-MS m/z [M+H]+ calc'd for C15H16FN5O2S, 350. found, 350.
