5-amino-1(2H)-phthalazinone → 5-{[2-Hydroxy-5-methoxy-2-(pentafluoroethyl)-4,4,7-trimethyl-1,2,3,4-tetrahydronaphthalen-1-yl]amino}-phthalazin-1-one

Participants

Reaction Steps

Analogously to Example 10, the corresponding imine is produced starting from 250 mg of 4-(2-methoxy-4-methyphenyl)-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.
