Reaction Steps
A solution of 74 ml of (R)-1-phenylethylamine in 100 ml of dioxane is dropped into 108.8 g of 4-chloro-6-nitro-7-fluoro-quinazoline in 800 ml of methylene chloride with cooling. The reaction mixture is washed with water after stirring overnight at room temperature, the organic phase is separated, dried and evaporated. The obtained residue is purified by chromatography over a silica gel column (petroleum ether/ethyl acetate=1:1). Yield: 52.9 g (35% of theory); melting point: 203° C.; mass spectrum (ESI+): m/z=313 [M+H]+.
