Using an analogous procedure to that described in Example 4, 4-chloro-6-methoxy-7-(1-methylpiperidin-4-ylmethoxy)quinazoline (246 mg, 0.764 mmol), (prepared as described for the starting material in Example 2c), was reacted with 4-chloro-2,6-difluoroaniline (250 mg, 1.53 mmol), (see WO 97/30035 Example 15), in DMF (9 ml) and in the presence of sodium hydride (60%, 76.5 mg, 1.9 mmol) to give 4-(4-chloro-2,6-difluoroanilino)-6-methoxy-7-(1-methylpiperidin-4-ylmethoxy)quinazoline (210 mg, 61%).
