Versuchsvorschrift
From 6-Methoxy-4-methyl-8-phthalimido-5-(3-trifluoromethylphenoxy)quinoline-2-one Ethanolate (IV): A solution of 6-methoxy-4-methyl-8-phthalimido-5-(3-trifluoromethylphenoxy)quinoline-2-one ethanolate (1 g, 1.85 mmol) in CHCl3 (10 mL) was treated with POCl3 (1.5 mL, 2.5 g, 16.4 mmol) as described above to give, after recrystallization from EtOH, 0.3 g (32%) of title compound, mp 225°-227° C. Further recrystallization from EtOH raised the mp to 227°-229° C. [mixed mp with material prepared in A) 226°-229° C⟧
