Versuchsvorschrift

4-Mercaptopyridine (93 mg) was added to a suspension of sodium hydride 60% (12 mg) in DMF (2 ml) under nitrogen. After stirring for 15 minutes 4-(4-bromo-2-fluorophenylamino)-7-(2,3-epoxypropoxy)-6-methoxyquinazoline (100 mg) (from Example 5) was added and the mixture was stirred for 3 hours at ambient temperature. The volatiles were removed under vacuum. The residue was partitioned between methylene chloride and water and the pH of the aqueous layer was adjusted to 7 with 1N HCl. The organic layer was separated, washed with water, followed by brine, dried (MgSO4) and evaporated to give 4-(4-bromo-2-fluorophenylamino)-7-[2-hydroxy-3-(4-pyridylsulphanyl)propoxy]-6-methoxyquinazoline (20 mg).
