Procedure

Using a method analogous to that in Example 25, 4-(4-chloro-2-fluoroanilino)-6-methoxy-7-(3-methylthiopropoxy)quinazoline (250 mg, 0.6 mmol), (prepared as described in Example 21), was treated with OXONE, (trade mark of E.I. du Pont de Nemours & Co., Inc), (84 mg) and the product was purified and isolated to give 4-(4chloro-2-fluoroanilino)6-methoxy-7-(3-methylsulphinylpropoxy)quinazoline (75 mg, 29%).
