3-Fluoro-N-[4-(2-methylsulfanyl-pyrimidin-4-yloxy)-naphthalen-1-yl]-5-morpholin-4-yl-benzamide (457 mg, 0.908 mmol) and MCPBA (447 mg, 1.998 mmol) in CHCl3 (5 ml) is stirred at room temperature for 1 h. The mixture is diluted with CHCl3 (5 ml) washed with sat'd NaHCO3 solution (5 ml), water (5 ml), dried over Na2SO4 and concentrated to give a yellow solid. The yellow solid is mixed with N,N,2,2-tetramethyl-1,3-propanediamine (1.18 g, 9.08 mmol) and DIPA (1.58 ml, 9.08 mmol) in DMSO (2 ml), and heated to 85° C. for 4 h. The resulting mixture is diluted with CH2Cl2 (2 ml), washed with 0.01 N NaOH, dried over Na2SO4, concentrated. The residue is purified by column chromatography on silica gel (EtOAc) to give N-{4-[2-(3-dimethylamino-2,2-dimethyl-propylamino)-pyrimidin-4-yloxy]-naphthalen-1-yl}-3-fluoro-5-morpholin-4-yl-benzamide as a white solid (60 mg). 1H NMR (400 MHz, CDCl3) δ 8.19 (s, 1H), 8.08 (s, 1H), 8.01 (d, 1H), 7.92 (m, 2H), 7.57 (t, H), 7.51 (t, 1H), 7.30 (d, 2H), 7.21 (d, 1H), 6.82 (dt, 1H), 5.87 (s, 1H), 4.33 (m, 1H), 3.23 (s, 1H), 2.27 (s, 6H), 2.21 (m, 2H), 2.02 (m, 2H), 1.82 (m, 2H), 1.57 (m, 3H), 1.39 (m, 3H), 0.98 (s, 6H); MS 586.37 (M+1).
