To a stirred solution of 5-amino-1-(1-(7-methoxyquinolin-4-yloxy)-2-methylpropan-2-yl)pyridin-2(1 H)-one (33 mg, 97 μmol) in CH2Cl2 (3 mL) and tBuOH (1 mL) at 0° C. under nitrogen was added DIEA (17 μl, 97 μmol) followed by a solution of benzoyl chloride (11 μl, 97 μmol) in CH2Cl2 (0.5 mL). The reaction mixture was stirred for 24 h at 23° C. and partitioned between CH2Cl2 (10 mL) and 5% NaHCO3 (5 mL). The organic was dried over MgSO4, concentrated onto dry silica, and purified on silica (12 g) eluting with 0-5% MeOH/CH2Cl2. MS (ESI pos. ion) m/z (MH+): 444.
