Reaction Steps

A mixture of 4-amino-1-[1-[1-(4-fluorophenyl)-5-isopropylpyrazol-4-yl]-2-oxo-pyrrolidin-3-yl]pyrazolo[3,4-d]pyrimidine-3-carbonitrile (0.055 g, 0.12 mmol) in ethane-1,2-diamine (1.5 mL), HOAc (0.23 mL), and EtOH (2.0 mL) was stirred at 100° C. for 45 min. The mixture was then cooled to room temperature, quenched with sat. aq. NaHCO3 (50 mL), and extracted with IPA:CHCl3 (1:2 v/v, 100 mL). The organic layer was separated, dried over anhydrous sodium sulfate and concentrated in vacuo to afford 3-[4-amino-3-(4,5-dihydro-1H-imidazol-2-yl)pyrazolo[3,4-d]pyrimidin-1-yl]-1-[1-(4-fluorophenyl)-5-isopropylpyrazol-4-yl]pyrrolidin-2-one (0.057 g, 97%).
