Reaction Steps

To a solution of tert-butyl ((1R,3R)-3-((2-((3-chlorophenethyl)amino)-5-cyanopyrimidin-4-yl)amino)-2,2-dimethylcyclobutyl)carbamate (102 mg, 0.22 mmol) in dry DCM (2 mL) was added TFA (1.5 mL) dropwise under cooling in an ice-water bath. The resulting mixture was stirred at room temperature for 30 min. After removal of the organic solvent, the residue was neutralized with ammonia and extracted with DCM. The combined organic layers were dried over anhydrous sodium sulfate and concentrated to give the crude, which was purified by standard methods to afford the title compound (43.8 mg, 0.118 mmol, 54% yield). 1H NMR (400 MHz, CD3OD) δ (ppm) 8.06 (s, 1H), 7.29-7.15 (m, 4H), 4.33 (dd, J1=5.6 Hz, J2=9.2 Hz, 1H), 3.72-3.50 (m, 2H), 3.18-3.12 (m, 1H), 2.93-2.86 (m, 2H), 2.45-2.39 (m, 1H), 2.17-2.12 (m, 1H), 1.20 (s, 3H), 0.98 (s 3H). MS (ESI) m/z 371.2 [M+H]+.
