実験手順
Using an analogous procedure to that described for the starting material in Example 1, 4-(3-acetoxy-4-methylanilino)-7-hydroxy-6-methoxyquinazoline hydrochloride (400 mg) was reacted in the presence of catalytic potassium iodide with 3-chloromethylthiophene (Journal of the Chemical Society 1958, 4202) (168 mg) to give 4-(3-acetoxy-4-methylanilino)-6-methoxy-7-(3-thienylmethoxy)quinazoline (210 mg, 46%).
