Procedure

A solution of cis-tert-butyl 2-(2-(2,4-dimethoxybenzyl)-7-fluoro-4-(1-methyl-1H-pyrazol-4-yl)-3-oxo-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-6-ylamino)cyclohexylcarbamate (109 mg, 0.183 mmol) in TFA (5 mL) was heated at 60° C. for 2 h. After removal of the solvent, the residue was diluted in MeOH (2 mL) and was purified by preparative HPLC. The fractions were collected and stripped to dryness via rotary evaporation to give the title compound as a TFA salt. 1H NMR (500 MHz, DMSO-d6) δ ppm 1.47 (br s, 2 H), 1.57-1.75 (m, 3 H), 1.84 (br s, 2 H), 3.12-3.23 (m, 2 H), 3.87-3.94 (m, 3 H), 4.35-4.50 (m, 3 H), 6.73 (br s, 1 H), 7.71 (br s, 2 H), 8.28-8.44 (m, 2 H), 8.84 (d, J=3.91 Hz, 1 H). [M+H] calc'd for C17H21FN6O, 345; found, 345.
