Participants

Reaction Steps

A flask was charged with 8′-chloro-6′-((5-((trimethylsilyl)ethynyl)pyrimidin-4-yl)amino)-2′H-spiro[cyclohexane-1,3′-imidazo[1,5-a]pyridine]-1′,5′-dione (5, 300 mg, 0.67 mmol) and methanol (20 mL) followed by addition of potassium carbonate (469 mg, 3.39 mmol) at room temperature and reaction mixture was stirred for 16 h. After completion, solvent was concentrated under reduced pressure and the resulting residue was further washed with water followed by diethyl ether and pentane to afford 8′-chloro-6′-((5-ethynylpyrimidin-4-yl)amino)-2′H-spiro[cyclohexane-1,3′-imidazo[1,5-a]pyridine]-1′,5′-dione (Cpd. No. 144) as yellow solid. Yield: 100 mg, 40%; MS (ESI) m/z 370.09 [M+1]+; 1H NMR (400 MHz, DMSO-d6) δ 10.42 (s, 1H), 8.99 (s, 1H), 8.90 (s, 1H), 8.70 (s, 2H), 5.22 (s, 1H), 2.90 (brs, 2H), 1.73-1.64 (m, 2H), 1.61-1.56 (m, 3H), 1.56-1.53 (m, 2H), 1.27 (m, 1H).
