Participants

Reaction Steps

To a solution of 5-(4-bromo-phenyl)-6-(2-fluoro-phenyl)-1,5-dihydro-pyrazolo[3,4-d]pyrimidin-4-one (20.0 mg, 0.052 mmol) in anhydrous pyridine (0.5 mL) is added 4-morpholinecarbonyl chloride (7.27 μL, 0.062 mmol). The mixture is stirred at room temperature for 2 h before removal of the solvent. The residue is purified by preparative LCMS followed by preparative TLC to provide the title compound (9.1 mg, 35% yield) as a white solid product; 1H NMR (CDCl3, 400 MHz) δ 8.91 (s, 1H), 7.42-7.28 (m, 4H), 7.11 (t, 1H), 7.02 (d, 2H), 6.88 (t, 1H), 4.15-3.84 (m, 8H); HPLC-MS calculated for C22H17BrFN5O3 (M+H+) 498.0. Found: 498.0.
