Iodoethane → Isopropyl 4,6-diamino-2-[1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]-5-pyrimidinyl(ethyl)carbamate

Participants

Reaction Steps

Prepared in analogy to Example 6 with 60 mg (0.14 mmol) of isopropyl 4,6-diamino-2-[1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]-5-pyrimidinylcarbamate from Example 3, 4.95 mg (0.21 mmol) of sodium hydride and 21.4 mg (0.17 mmol) of iodoethane. To complete the reaction, the same amount of sodium hydride and iodoethane are added once again. The residue is purified by preparative RP-HPLC.
