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

Participants

Reaction Steps

Analogously to Example 10, the corresponding imine is produced starting from 200 mg of 4-(2-methoxy-4-methylphenyl)-2-hydroxy-4-methyl-2-(pentafluoroethyl)pentanal and 93 mg of 5-aminoquinolin-2(1H)-one. 2 mg of the title compound is obtained by reaction of 80 mg of the imine with 1.6 ml of titanium tetrachloride solution (1 M in dichloromethane) in 5 ml of dichloromethane.
