Participants

Reaction Steps

Analogously to Example 10, the corresponding imine is produced starting from 500 mg of 4-(2-methoxyphenyl)-2-hydroxy-4-methyl-2-(trifluoromethyl)pentanal and 277 mg of 5-amino-phthalazin-1-one. As in Example 2, 32 mg of 5-{[2-hydroxy-4,4-dimethyl-5-methoxy-2-(trifluoromethyl)-1,2,3,4-tetrahydronaphthalen-1-yl]amino}-phthalazin-1(2H)-one as fraction 1 and 35 mg of 5-{[2,5-dihydroxy-4,4-dimethyl-2-(trifluoromethyl)-1,2,3,4-tetrahydronaphthalen-1-yl]amino}-phthalazin-1(2H)-one as fraction 3 are obtained by reaction of 470 mg of imine with 5.4 ml of BBr3 (1 M in dichloromethane).
