Reaction Steps

A solution of tert-butyl (1S,2R)-2-(7-fluoro-4-(1-methyl-1H-pyrazol-4-yl)-3-oxo-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-6-ylamino)cyclohexylcarbamate (15 mg, 0.034 mmol) and TFA (0.5 mL, 6.49 mmol) in DCM (0.5 mL) was stirred at RT for 30 min. The reaction mixture was concentrated and the resulting residue was purified by preparative HPLC to give a TFA salt of the title compound (7 mg, 60.2%). 1H NMR (500 MHz, DMSO-d6) δ ppm 1.37-2.01 (m, 8H), 3.67 (br s, 1H), 3.89 (s, 3H), 4.32-4.43 (m, 2H), 4.45 (br s, 1H), 6.77 (d, J=6.35 Hz, 1H), 7.93 (br s, 3H), 8.30 (s, 1H), 8.36 (s, 1H), 8.84 (s, 1H). [M+H] calc'd for C17H21FN6O, 345. found, 345.
