Reaction Steps

A round-bottom flask was charged with tert-butyl (4-(5-((S)-1-((2-amino-5-cyano-6-methylpyrimidin-4-yl)amino)ethyl)-1-methyl-1H-pyrrolo[3,2-b]pyridin-6-yl)cyclohex-3-en-1-yl)carbamate (0.079 g, 0.157 mmol), DCM (2 mL), and TFA (0.969 mL, 12.57 mmol). The reaction mixture was stirred at room temperature for 30 minutes. The solvent was evaporated using a stream of nitrogen. A portion of the crude material was purified via preparative HPLC (acid mode, 5-25% ACN/water gradient). The product-containing fractions were dried in vacuo to give the title compound as an off-white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 0.81 (d, J=6.82 Hz, 3H), 0.97-1.16 (m, 1H), 1.30-1.51 (m, 2H), 1.57 (s, 3H), 1.63-1.94 (m, 3H), 2.66 (d, J=8.84 Hz, 1H), 3.07-3.15 (m, 3H), 4.69-4.88 (m, 1H), 5.02 (br s, 1H), 5.86 (d, J=3.03 Hz, 1H), 7.05 (d, J=3.03 Hz, 1H), 7.45 (d, J=4.04 Hz, 1H); ESI-MS m/z [M+H]+ calc'd for C22H26N8, 403. found 403.
