Sodium hydride → 3-Iodo-1-((8-methyl-2-o-tolylquinolin-3-yl)methyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine

Participants

Reaction Steps

Prepared according to Procedure I. A solution of 3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (400 mg, 1.5 mmol) in DMF (5 mL) at 0° C. was treated with NaH (60%, 67.4 mg, 1.1 eq) for 30 min before addition of a solution of 3-(chloromethyl)-8-methyl-2-o-tolylquinoline (435 mg, 1 eq) in DMF (2 mL). The mixture was stirred at room temperature over night. The reaction mixture was partitioned between DCM (50 mL) and water (50 mL). The insoluble was filtered and washed with DCM and water. The organic layer from the filtrate was separated, dried over Na2SO4, concentrated and purified by column chromatography on silica gel (eluent: DCM/MeOH, 25/1) to provide a white solid [PI3Kδ IC50=6 nM]. 1H-NMR (DMSO-d6) δ 7.96 (s, 1H), 7.85 (s, 1H), 7.63 (d, J=8.2 Hz, 1H), 7.44 (d, J=7.0 Hz, 1H), 7.31 (t, J=7.1 Hz, 1H), 6.94-6.99 (m, 4H), 5.26 (s, 2H), 2.45 (s, 3H), 1.79 (s, 3H). Mass Spectrum (ESI) m/e=507 (M+1).
