Using a procedure analogous to that described in Example 34, 4-chloro-6-methoxy-7-(3-methylsulphonylpropoxy)quinazoline (150 mg, 0.45 mol) was reacted with 3-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-5-one (105 mg, 0.54 mol), (prepared as described for the starting material in Example 10), to give 4-(5-(4-methoxyphenyl)pyrazol-3-yloxy)-6-methoxy-7-(3-methylsulphonylpropoxy)quinazoline (220 mg, 91%).
