Procedure
A suspension of 1-(4-chloro-5-(1-ethyl-7-(2-methoxyethylamino)-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2-fluorophenyl)-3-(2-fluorophenyl)urea (0.220 g, 0.417 mmol) in MeCN (10 mL) was treated with methanesulfonic acid (0.040 g, 0.417 mmol) and stirred at RT for 20 h. The solids were filtered, washed and dried to provide 1-(4-chloro-5-(1-ethyl-7-(2-methoxyethylamino)-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2-fluorophenyl)-3-(2-fluorophenyl)urea methanesulfonate (205 mg, 79% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6): δ 9.22 (s, 1H), 9.10 (s, 1H), 8.54 (s, 1H), 8.25 (d, J=9 Hz, 1H), 8.18 (br s, 1H), 8.10 (m, 1H), 7.89 (s, 1H), 7.60 (d, J=11 Hz, 1H), 7.23 (m, 1H), 7.10 (m, 1H), 7.00 (m, 1H), 6.72 (s, 1H), 4.14 (m, 2H), 3.56 (m, 4H), 3.30 (s, 3H), 2.31 (s, 3H), 1.20 (t, J=6 Hz, 3H); MS (ESI) m/z: 528.2 [M+H]+.
