Reaction Steps

To a solution of 5-allyl-7-methoxy-4-phenylamino-quinazolin-6-ol (0.16 g, 0.524 mmol) (from Example 15, Step D, supra) in acetone (30 mL) was added K2CO3 (0.36 g, 2.62 mmol) and methyl iodide (0.15 g, 1.05 mmol) (Aldrich). The reaction mixture was heated with stirring at 90° C. for 4 hours. The mixture was cooled to room temperature, filtered and the filtrate was concentrated. The residue was purified by chromatography using EtOAc/CH2Cl2/Et3N (1:5:0.05) as eluent to give the desired (5-allyl-6,7-dimethoxy-quinazolin-4-yl)-phenyl-amine as a pale yellow solid. (Yield 0.13 g, 77%).
