실험 절차

Carbonyldiimidizole (0.28 mmol, 46 mg), and cyclohexanol (0.28 mmol, 34 μL) were dissolved in DMF (2 mL) and stirred for 30 minutes at room temperature. Then, 1-(4-Methanesulfonyl-phenyl)-4-(piperidin-4-yloxy)-1H-pyrazolo[3,4-d]pyrimidine hydrochloride salt (0.16 mmol, 60 mg) and triethylamine (0.84 mmol, 118 μL) were added and continued to stir at 60° C. for 24 hours. The reaction mixture was quenched with water followed by an extraction with ethylacetate. Removal of organic solvents in vacuo and purification by HPLC provided compound A63 as a white solid. 1H NMR (400 MHz, CDCl3) δ (ppm): 8.67 (s, 1H); 8.61 (d, 2H); 8.26 (s, 1H); 8.11 (d, 2H); 5.62 (h, 1H); 4.71 (h, 1H); 3.91 (m, 2H); 3.38 (m, 2H); 3.10 (s, 3H); 2.10 (m, 2H); 1.87 (m, 4H), 1.65 (m, 6H); 1.28 (m, 2H). LCMS (ESI), m/z 500.4 (MH+, 100%)
