Reaction Steps

Na (1.4 g, 0.060 mol) was carefully dissolved in 80 ml of anhydrous ethanol to form a clear solution, then N-(3-ethynylphenyl)-7-fluoro-6-nitroquinazolin-4-amine (8 g, 0.025 mol) was added and stirred for 4 hours at 80° C. The solution was concentrated under reduced pressure to remove excess ethanol, and 50 ml H2O was added. The resulting solid precipitate was filtered and dried under vacuum to get 7-ethoxy-N-(3-ethynylphenyl)-6-nitroquinazolin-4-amine as yellow solid 8.1 g (93.4% yield).
