Reaction Steps
A solution of 1-(3-chloro-5-fluorophenyl)-3-(5-(1-ethyl-7-((4-methoxybenzyl)(methyl)amino)-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2-fluoro-4-methylphenyl)urea (0.105 g, 0.170 mmol) in TFA (3 mL) was treated with anisole (0.093 ml, 0.849 mmol) and stirred at RT for 4 h. The mixture was concentrated to dryness and purified via reverse-phase chromatography (MeCN/H2O with 0.1% TFA). The combined fractions were neutralized with satd. NaHCO3, extracted with EtOAc (2×) and the combined organics were washed with water, then brine, dried over Na2SO4 and concentrated to dryness to afford 1-(3-chloro-5-fluorophenyl)-3-(5-(1-ethyl-7-(methylamino)-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2-fluoro-4-methylphenyl)urea (62 mg, 73% yield). 1H NMR (400 MHz, DMSO-d6): δ 9.54 (s, 1H), 8.69 (s, 1H), 8.40 (s, 1H), 7.85 (d, J=8.4 Hz, 1H), 7.66 (s, 1H), 7.35 (s, 1H), 7.27 (dt, J=11.3, 2.1 Hz, 1H), 7.14 (d, J=12.1 Hz, 1H), 7.00-6.95 (m, 2H), 6.24 (s, 1H), 4.14 (q, J=7.1 Hz, 2H), 2.85 (d, J=4.9 Hz, 3H), 2.07 (s, 3H), 1.21 (t, J=7.0 Hz, 3H); MS (ESI) m/z: 498.2 [M+H]+.
