Trifluoroacetic acid → HCID 118162184, compound

Participants

Reaction Steps

To a solution of tert-butyl ((1R,3S)-3-((2-((3-chlorophenethyl)amino)-5-cyanopyrimidin-4-yl)amino)-2,2-dimethylcyclobutyl)carbamate (82 mg, 0.17 mmol) in dry DCM (2 mL) was added trifluoroacetic acid (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 product, which was purified by standard methods to afford the title compound (34.3 mg, 0.092 mmol, 55% yield). 1H NMR (400 MHz, CD3OD) δ (ppm) 8.04 (s, 1H), 7.27-7.14 (m, 4H), 4.16-3.97 (m, 1H), 3.74-3.49 (m, 2H), 2.90-2.85 (m, 3H), 2.60-2.49 (m, 1H), 1.92-1.86 (m, 1H), 1.22 (s, 3H), 0.92 (s 3H). MS (ESI) m/z 371.2 [M+H]+.
