실험 절차

1-(4-methanesulfonyl-phenyl)-4-(piperidin-4-yloxy)-1H-pyrazolo[3,4-d]pyrimidine hydrochloride salt (0.17 mmol, 70 mg), ethylchloroformate (0.25 mmol, 25 μL) and triethylamine (0.51 mmol, 72 μL) were dissolved in DMF (2 mL) and stirred for 60 minutes at room temperature. Progress of the reaction was monitored by TLC and LCMS. The reaction mixture was quenched with water. The product was extracted with ethyl acetate. Removal of organic solvents in vacuo and purification by HPLC provided compound A123 as a white solid (14 mg, 15%). Exact mass calculated for C20H23N5O5S 445.49, found 446.10 (MH+).
