Phenyl chloroformate → HCID 59813257, compound

Participants

Reaction Steps

6-(6,7-Dimethoxyquinolin-4-yloxy)naphthalen-1-amine (80 mg, 0.231 mmol) was suspended in THF (1 mL), then added Hunig's base (33 mg, 0.254 mmol) and a solution of phenylchloroformate (36 mg, 0.231 mmol) in THF (0.5 mL). The reaction was stirred at RT for 16 h. A solution of cyclopropylamine (26 mg, 0.462 mmol) in THF (0.6 mL) was added to the mixture and the reaction was heated at 50° C. for 4 h. A precipitate formed and was collected on a glass frit, washed with THF then CH2Cl2. The tan solid was purified by preparative thin layer chromatography (8% MeOH in CH2Cl2) to give N-(6-((6,7-bis(methoxy)-4-quinolinyl)oxy)-1-naphthalenyl)-N′-cyclopropylurea as a white solid. MS (ESI, pos. ion) m/z: 430.2 (M+1). Mass Calc'd for C25H23N3O4: 429.47
