Thionyl Chloride → N-{4-[(6,7-Dimethoxy-4-quinazolinyl)oxy]phenyl}-N'-[(6-methyl-3-pyridyl)carbonyl]thiourea

온도

100 °C

Toluene (20 ml) and thionyl chloride (1 ml) were added to commercially available 6-methylnicotinic acid (80 mg), and the mixture was heated at 100° C. for one hr. The solvent was removed by distillation, and 6-methyl-3-pyridinecarbonyl isothiocyanate was prepared using the resultant 6-methyl-3-pyridinecarbonyl chloride as a starting compound according to the description of the literature. 4-[(6,7-Dimethoxy-4-quinazolinyl)oxy]aniline (50 mg) was dissolved in toluene (5 ml) and ethanol (1 ml) to prepare a solution. A solution of 6-methyl-3-pyridinecarbonyl isothiocyanate in ethanol (1 ml) 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 (71 mg, yield 89%).
