Reaction Steps

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-phenylurea, (0.233 g, 0.457 mmol) in MeCN (10 mL) was treated with methanesulfonic acid (0.044 g, 0.457 mmol). The crystallized 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-phenylurea methanesulfonate as a white solid (0.210 g, 76% yield). 1H NMR (400 MHz, DMSO-d6): δ 9.13 (s, 1H), 8.70 (s, 1H), 8.54 (s, 1H), 8.22 (d, J=9 Hz, 2H), 7.90 (s, 1H), 7.58 (d, J=12 Hz, 1H), 7.42 (d, J=8 Hz, 2H), 7.26 (t, J=8 Hz, 2H) 6.97 (t, J=8.5 Hz, 1H), 6.74 (s, 1H), 4.16 (m, 2H), 3.57 (m, 4H), 3.29 (s, 3H), 2.34 (s, 3H), 1.20 (t, J=6 Hz, 3H); MS (ESI) m/z: 510.2.2 [M+H]+.
