Reaction Steps

To a mixture of 3-amino-4-(dimethylamino)-N-methylbenzenesulfonamide (0.100 g, 0.434 mmol) and 4-chloro-6,7-bis(methyloxy)quinazoline (0.075 g, 0.334 mmol) in isopropanol (2 mL) was added HCl (0.334 mL, 0.334 mmol). The resulting mixture was then subjected to microwave irradiation (150° C., 6 bar) for 15 minutes. The mixture was then concentrated and purified via column chromatography (5-10% MeOH/CH2Cl2) to give an orange solid that was triturated with EtOAc and dried to afford 3-{[6,7-bis(methyloxy)-4-quinazolinyl]amino}-4-(dimethylamino)-N-methylbenzenesulfonamide (54 mg, 35% yield) as orange crystals.
