Procedure

A suspension of 1-(4-chloro-3-(1-ethyl-7-(methylamino)-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)phenyl)-3-phenylurea (0.166 g, 0.371 mmol) in refluxing MeCN (5 mL) was treated with methanesulfonic acid (0.026 mL, 0.408 mmol), cooled to RT, treated with water, frozen and lyophilized. The resulting material was treated with EtOAc, sonicated and collected via filtration to afford 1-(4-chloro-3-(1-ethyl-7-(methylamino)-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)phenyl)-3-phenylurea methanesulfonate (172 mg, 85% yield). 1H NMR (400 MHz, DMSO-d6): δ 8.96 (s, 1H), 8.81 (s, 1H), 8.54 (s, 1H), 8.08 (br s, 1H), 7.89 (s, 1H), 7.62 (t, J=1.4 Hz, 1H), 7.45-7.39 (m, 4H), 7.25 (t, J=7.8 Hz, 2H), 6.95 (t, J=7.3 Hz, 1H), 6.57 (s, 1H), 4.18 (q, J=7.1 Hz, 2H), 2.97 (s, 3H), 2.33 (s, 3H), 1.22 (t, J=7.0 Hz, 3H); MS (ESI) m/z: 448.1 [M+H]+.
