Reaktionsschritte
A mixture of 2.00 g (6.28 mmol) 4-(4-isopropyl-phenyl)-6-prop-2-ynyloxy-1H-quinazolin-2-one, 0.72 ml (6.28 mmol) epoxy-styrene, 0.143 g (0.628 mmol) benzyl-triethylammonium chloride (TEBA), 0.086 g (0.628 mmol) potassium carbonate and 5 ml dioxane is heated at 90° C. for 18 h. Aqueous work up followed by chromatography on silica gives 1-(2-hydroxy-2-phenyl-ethyl)-4-(4-isopropyl-phenyl)-6-prop-2-ynyloxy-1H-quinazolin-2-one.
