Reaction Steps

To a solution of ethylene glycol (3.05 mL, 55.6 mmol) in N,N-dimethylformamide (50 mL) at room temperature was added sodium hydride (60% dispersion in oil, 0.30 g, 7.50 mmol) portion-wise. The reaction mixture was allowed to stir at room temperature for 30 minutes. A solution of 5-fluoro-2-methylquinazoline (2.22 g, 55.6 mmol) in N,N-dimethylformamide (5 mL) was added and the reaction mixture heated at 85° C. for 14 h. The mixture was allowed to cool to room temperature, quenched by the addition of water and concentrated in vacuo. Chromatography of the residue on SiO2 eluting with 40% ethyl acetate in dichloromethane to ethyl acetate gave the title compound as a yellow solid (0.39 g, 10%).
