Reaction Steps

Analogously to Example 10, the corresponding imine is produced starting from 600 mg of 4-(2-methoxy-4-methylphenyl)-2-hydroxy-4-methyl-2-(trifluoromethyl)pentanal and 315 mg of 5-aminoquinolin-2(1H)-one. 12 mg of the title compound is obtained by reaction of 370 mg of the imine with 8.3 ml of titanium tetrachloride (1 M in dichloromethane) in 20 ml of dichloromethane.
