Procedure
A mixture of 1-(benzo[b]thiophen-3-yl)-3-(5-(7-chloro-1-ethyl-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2-fluoro-4-methylphenyl)urea (0.23 g, 0.454 mmol), Cs2CO3 (0.443 g, 1.361 mmol), N,N-dimethylurea (0.200 g, 2.268 mmol) and Xantphos (0.079 g, 0.136 mmol) in dioxane (10 mL) was sparged with Ar, treated with Pd2(dba)3 (0.062 g, 0.068 mmol), sparged again with Ar and heated at 100° C. overnight. The mixture was cooled to RT, the solids removed via filtration and rinsed with water and EtOAc. The layers of the filtrate were separated, the organic layer washed with brine, dried over Na2SO4 and concentrated to dryness. The material was treated with DCM, the solid removed via filtration and the filtrate purified via silica gel chromatography (EtOAc/Hex) to afford 3-(3-(5-(3-(benzo[b]thiophen-3-yl)ureido)-4-fluoro-2-methylphenyl)-1-ethyl-2-oxo-1,2-dihydro-1,6-naphthyridin-7-yl)-1,1-dimethylurea (25 mg, 9% yield). 1H NMR (400 MHz, DMSO-d6): δ 9.34 (s, 1H), 9.13 (s, 1H), 8.79 (s, 1H), 8.60 (s, 1H), 8.03 (d, J=8.4 Hz, 1H), 7.97 (s, 1H), 7.91 (d, J=8.0 Hz, 1H), 7.83 (m, 2H), 7.62 (s, 1H), 7.45-7.40 (m, 1H), 7.36 (t, J=7.5 Hz, 1H), 7.15 (d, J=12.3 Hz, 1H), 4.14 (d, J=8.0 Hz, 2H), 2.93 (s, 3H), 1.20 (m, 3H); MS (ESI) m/z: 559.2 [M+H]+.
