Procedure

To a suspension of 1-(4-bromo-5-(1-ethyl-7-(2-methoxyethylamino)-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2-fluorophenyl)-3-phenylurea (0.200 g, 0.361 mmol) in MeCN (4 mL) was added methanesulfonic acid (0.035 g, 0.361 mmol) and the mixture was stirred at RT for 30 minutes. The solvent was completely evaporated and the residue was crystallized from MeCN to provide 1-(4-bromo-5-(1-ethyl-7-(2-methoxyethylamino)-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2-fluorophenyl)-3-phenylurea methanesulfonate (0.160 g, 67% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6): δ 9.23 (s, 1H), 9.04 (s. 1H), 8.53 (s, 1H), 8.22 (d, J=9 Hz, 2H), 7.87 (s, 1H), 7.70 (d, J=11 Hz, 1H), 7.41 (d, J=9 Hz, 2H), 7.26 (t, J=7 Hz, 2H), 6.96 (t, J=7 Hz, 1H), 6.72 (s, 1H), 4.13 (m, 2H), 3.56 (m, 4H), 3.30 (s, 3H), 2.33 (s, 3H), 1.21 (d, J=6 Hz, 3H); MS (ESI) m/z: 554.1/556.1 [M+H]+.
