실험 절차

1-(4-Methanesulfonyl-phenyl)-4-(piperidin-4-yloxy)-1H-pyrazolo[3,4-d]pyrimidine hydrochloride (0.17 mmol, 60 mg), n-butyl chloroformate (0.19 mmol, 24 μL) and triethylamine (0.51 mmol, 71 μL) were dissolved in DMF (2 mL) and stirred for 60 minutes at room temperature. The reaction mixture was quenched with water followed by an extraction with ethylacetate. Removal of organic solvents in vacuo provided Compound A48 as a white solid (40 mg, 50%). 1H NMR (400 MHz, CDCl3) δ (ppm): 8.67 (s, 1H); 8.62 (d, 2H); 8.26 (s, 1H); 8.11 (d, 2H); 5.62 (h, 1H); 4.12 (t, 2H); 3.92 (m, 2H); 3.39 (m, 2H); 3.10 (s, 3H); 2.11 (m, 2H); 1.65 (m, 2H), 1.56 (p, 2H); 1.42 (s, 2H); 0.97 (t, 3H). Exact mass calculated for C22H27N5O5S 473.55, found 474.4 (MH+).
