Reaction Steps

4-(6-Amino-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-2-bromo-6-fluoro-phenol hydrochloride (Example 42b) (30 mg, 0.08 mmol) is dissolved in DMF (1 ml) then treated with K2CO3 (24 mg, 0.18 mmol) and 2-bromoethyl methyl ether (7.5 μL, 0.08 mmol). The reaction mixture is heated at 120° C. for 3 hours then cooled to room temperature, diluted with MeOH and concentrated in vacuo. The crude residue is dry loaded onto silica and purification by flash chromatography on silica eluting with iso-hexanes:EtOAc (50% EtOAc to 100% EtOAc) affords the title compound as an off-white soild.
