Participants

Reaction Steps

A mixture of tert-butyl (1S,2R)-2-(4-(3-(methylsulfonyl)phenylamino)-3-oxo-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-6-ylamino)cyclopentylcarbamate (16.5 mg, 0.329 mmol) and HCl (1 mL, 32.9 mmol) in HOAc (2 mL) was stirred at RT for 3 h. The mixture was concentrated under reduced pressure and the residue was recrystallized from EtOH-H2O to give the title compound (9.6 mg, 67%). 1H-NMR (DMSO-d6) δ ppm 1.63-1.79 (m, 4H), 20.3-2.06 (m, 1H), 2.19-2.20 (m, 1H), 3.32 (s, 3H), 3.74 (br s, 1H), 4.23-4.28 (m, 2H), 4.45 (br s, 1H), 6.22 (s, 1H), 7.34-7.35 (m, 1H), 7.51-7.58 (m, 3H), 7.73 (br s, 3H), 8.13 (s, 1H), 8.82 (s, 1H), 9.26 (s, 1H).
