Ethanol → N-(2-Chlorobenzoyl)-N'-{3-chloro-4-[(6,7-dimethoxy-4-quinazolinyl)oxy]phenyl}thiourea

Participants

Reaction Steps

3-Chloro-4-[(6,7-dimethoxy-4-quinazolinyl)oxy]aniline (50 mg) was dissolved in toluene (5 ml) and ethanol (1 ml) to prepare a solution. Commercially available 2-chloro-1-benzenecarbonyl isothiocyanate (50 μl) was then added to the solution, and the mixture was stirred at room temperature for 2 hr. The reaction solution was concentrated, and the residue was purified by chromatography on silica gel using chloroform/acetone for development to give the title compound (79 mg, yield 90%).
