Analogously to Example 10, the corresponding imine is produced starting from 250 mg of 4-(2-methoxy-4-methylphenyl)-2-hydroxy-4-methyl-2-(pentafluoroethyl)pentanal and 118 mg of 5-amino-phthalazin-1-one. As in Example 3, 65 mg of the imine is reacted by reaction with 0.38 ml of titanium tetrachloride (1 M in dichloromethane) in 6 ml of dichloromethane, and 8 mg of the title compound is obtained.
