実験手順

To a suspension of 7-(2-fluoro-4-iodophenylamino)-8-fluoro-4-methylquinazoline-6-carboxylic acid (190 mg, 0.47 mmol) in toluene (10 ml) was added triethylamine (0.19 ml, 1.41 mmol) and diphenylphosphoryl azide (0.20 ml, 0.94 mmol). The reaction was heated at reflux for 4 h. The mixture was cooled to room temperature and concentrated to dryness. Silica gel chromatography (EtOAc:Hexane=75:25) yields 143 mg (75%) of the title compound as a tan solid.
