Analogously to Example 10, the corresponding imine is produced starting from 1.0 g of 4-(3-chloro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-(trifluoromethyl)pentanal and 542 mg of 5-amino-2-methyl-phthalazin-1-one. As in Example 3, 840 mg of the imine is reacted by reaction with 43.6 ml of titanium tetrachloride (1 M in dichloromethane) in 40 ml of dichloromethane, and 114 mg of the title compound is obtained.
