실험 절차

In 800 ml of dioxane, 15 g (26.11 mmol) of methyl {8-fluoro-2-[4-(4-fluorophenyl)-1-piperazinyl]-3-[2-methoxy-5-(trifluoromethyl)phenyl]-3,4-dihydro-4-quinazolinyl}acetate (Example 30A) and 3.13 g (78.32 mmol) of sodium hydroxide are stirred at 50° C. for 4 hours. Following distillative removal of the solvent, the residue is dissolved in 500 ml of water and acidified and the precipitate is filtered off with suction. The product is washed with water and dried under reduced pressure.
