Reaction Steps

To a 25 ml round bottom flask is added potassium fluoride (82.6 mg, 1.42 mmol) and kryptofix 222 (0.53 g, 1.42 mmol). The above mixture is stirred in THF for 20 minutes after which 6-Nitro-4-(2-(4-tert-butylphenyl)ethoxy)quinazoline (0.1 g, 0.284 mmol) is added to it. The solution is refluxed for 30 minutes after which it is cooled and water is added to it. It is then extracted in dichloromethane, washed with water and dried. Purification by flash chromatography (silica gel; ethyl acetate/hexanes) gives the above compound.
