To a round bottom flask equipped with a magnetic stir bar was added 6-(6,7-dimethoxy-quinolin-4-yloxy)-pyridin-3-ylamine (85 mg, 0.0285 mmol, 1.0 eq.), and Phenyl-acetyl isothiocyanate (256 mg, 1.44 mmol, 5.0 eq.) dissolved in EtOAc/MeOH 50:50 (2 mL). The reaction mixture was stirred at room temperature for 12 hours, and the solvent was evaporated via rotary evaporation. Purification was done on Biotage with solvent system 95% EtOAc, 4% TEA and 1% MeOH. The combined pure fractions were concentrated and dried under vacuum overnight to yield 1-[6-(6,7-dimethoxy-quinolin-4-yloxy)-pyridin-3-yl]-3-phenylacetyl-thiourea as a light yellow solid (40.4 mg, 29.7%). 1H NMR (400 MHz, CDCl3): 8.65 (d, 1H), 8.33 (d, 1H), 8.27 (dd, 1H), 7.35 (m, 7H), 7.15 (d, 1H), 6.92 (d, 1H), 4.05 (s, 3H), 3.99 (s, 3H), 3.76 (s, 2H); MS (EI) for C25H22N4O4S: 475 (M+H+).
