Procedure

Using an analogous procedure to that described in Example 51, 7-(2-bromoethoxy)-4-(4-chloro-2-fluoroanilino)-6-methoxyquinazoline (98 mg, 0.23 mmol), (prepared as described for the starting material in Example 51), was treated with 5-mercapto-1-methyltetrazole (40 mg, 0.35 mmol) to give 4-(4-chloro-2-fluoroanilino)-6-methoxy-7-(2-(1-methyltetrazol-5-ylthio)ethoxy)-quinazoline hydrochloride (50 mg, 44%).
