Versuchsvorschrift

In 40 ml of dioxane, 892 mg (1.56 mmol) of methyl {8-fluoro-2-[4-(3-methylphenyl)-1-piperazinyl]-3-[2-methoxy-5-(trifluoromethyl)phenyl]-3,4-dihydro-4-quinazolinyl}acetate (Example 33A) and 187.6 mg (4.69 mmol) of sodium hydroxide are stirred at 50° C. for 2 hours. Following removal of the solvent, the residue is taken up in water and adjusted to pH 4-5 using 1N hydrochloric acid. The product is filtered off and then washed with water and dried under reduced pressure.
