Methanol → N-(sec-Butyl)-N'-{4-[(6,7-dimethoxy-4-quinazolinyl)oxy]-2-fluorophenyl}urea

Participants

Reaction Steps

4-[(6,7-Dimethoxy-4-quinazolinyl)oxy]-2-fluoroaniline (50 mg) was dissolved in chloroform (3 ml) and triethylamine (0.3 ml), and a solution of triphosgene (47 mg) in chloroform was then added to the solution. The mixture was stirred at room temperature for 30 min. Next, sec-butylamine (25 μl) was added to the reaction solution, and the mixture was further stirred at room temperature overnight. Methanol was added to the reaction solution, and the mixture was purified by HPLC by development with chloroform/methanol to give 12 mg (yield 18%) of the title compound.
