Procedure

A solution of Example A6 (0.200 g, 0.603 mmol) and TEA (0.126 mL, 0.904 mmol) in THF (6 mL) was treated with phenyl isocyanate (0.066 mL, 0.603 mmol and stirred at RT overnight. The resulting solid was collected via filtration and dried to afford 1-(5-(7-chloro-1-ethyl-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2-fluoro-4-methylphenyl)-3-phenylurea (211 mg, 78% yield). 1H NMR (400 MHz, DMSO-d6): δ 9.01 (s, 1H), 8.77 (s, 1H), 8.51 (d, J=2.3 Hz, 1H), 8.01-7.98 (m, 2H), 7.73 (s, 1H), 7.41 (dd, J=8.3, 1.2 Hz, 2H), 7.25 (dd, J=8.5, 7.3 Hz, 2H), 7.17 (d, J=12.2 Hz, 1H), 6.97-6.90 (m, 1H), 4.27 (q, J=7.1 Hz, 2H), 2.07 (s, 3H), 1.21 (t, J=7.0 Hz, 3H); MS (ESI) m/z: 451.1 [M+H]+.
