Compound (1F) (21 g, 0.06 mol) was suspended in ammonia (100 mL of 2.0 M solution in MeOH) and the solution formed after 30 min was stirred at room temperature for 18 h. The precipitate was filtered, the concentrated filtrate triturated with EtOAc, and the organic layers were combined to yield 21.5 g of 2-chloro-6-(2,4-difluorophenoxy)-quinazolin-4-ylamine (1G).
