Procedure

A mixture of Example 21 (90 mg, 0.199 mmol) and pyridine (79 mg, 0.996 mmol) in THF (4 mL) was treated drop-wise with methoxy acetyl chloride (27 mg, 0.249 mmol) and stirred at RT for 22 h. Additional methoxy acetyl chloride (30 μL, 0.328 mmol) was added, the mixture heated at 40° C. for 6 h, then cooled to RT and stirred overnight. The mixture was treated with EtOAc and water, stirred for 1 h, the resulting solid collected via filtration and dried to afford N-(3-(2-chloro-4-fluoro-5-(3-phenylureido)phenyl)-1-ethyl-2-oxo-1,2-dihydro-1,6-naphthyridin-7-yl)-2-methoxyacetamide (76 mg, 72% yield). 1H NMR (400 MHz, DMSO-d6): δ 10.39 (s, 1H), 9.09 (s, 1H), 8.73 (m, 2H), 8.27-8.20 (m, 2H), 8.00 (s, 1H), 7.58 (d, J=10.9 Hz, 1H), 7.41 (d, J=8.0 Hz, 2H), 7.26 (t, J=7.7 Hz, 2H), 6.97 (t, J=7.3 Hz, 1H), 4.21 (q, J=7.1 Hz, 2H), 4.12 (s, 2H), 3.38 (s, 3H), 1.26 (t, J=7.1 Hz, 3H); MS (ESI) m/z: 524.2 [M+H]+.
