Procedure

Part B: To a stirred solution of 300 mg (0.55 mmol) of 1-(2,4,6-trichlorophenyl)-3-isopropyl-6-(4-(chloroacetamido)benzyl)pyrazolo[3,4-d]pyrimidin-4-one in 6 mL of 1:1 DMF-THF was added 1 g of piperazine. The solution was stirred overnight at ambient temperature and poured into water. The mixture was extracted twice with EtOAc, and the combined organic extracts were washed (brine), dried (MgSO4), and concentrated under reduced pressure to afford 230 mg (71%) of 1-(2,4,6-trichlorophenyl)-3-isopropyl-6-(4-(piperazin-1-ylmethylcarbonylamino)benzyl)pyrazolo[3,4-d]pyrimidin-4-one as an off-white solid. Mass spec. (ESI+): 588 ((M+H)+).
