Versuchsvorschrift

A 15 ml round bottom flask charged with 4-(2-(4-(4-hydroxybutyl)phenyl)ethoxy) quinazoline (0.25 g, 0.77 mmol) is dissolved in pyridine (5 ml). p-Toluenesulfonyl chloride (0.15 g, 0.79 mmol) is then added to it and the mixture stirred for 4 hours. The reaction mixture is diluted with ethyl acetate, washed with 5% copper sulfate solution and then with water and dried. After removing the solvent on the rotary evaporator the crude is purified by flash chromatography using silica gel (ethyl acetate/hexanes) to give the product.
