실험 절차

To a solution of (5-allyl-6,7-dimethoxy-quinazolin-4-yl)-(4-bromo-2-fluoro-phenyl)-amine (0.236 g, 0.564 mmol) (from Example 19, Step E, supra) in dichloromethane (30 mL) was added I2 (1.43 g, 5.64 mmol). The reaction mixture was stirred at room temperature for 4 hours. The mixture was diluted with chloroform (100 mL), and washed with a saturated aqueous Na2SO3 solution. The organic layer was separated, dried over Na2SO4, and concentrated to give the desired 4-(4-bromo-2-fluoro-phenyl)-5-iodomethyl-7,8-dimethoxy-5,6-dihydro-4H-1,3,4-triaza-phenalene as an off white oil. (Yield 0.034 g, 11%).
