4-(3-Chloro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-(trifluoromethyl)pentanal → 5-{[6-Chloro-4,4-dimethyl-2-hydroxy-5-methoxy-2-(trifluoromethyl)-1,2,3,4-tetrahydronaphthalen-1-yl]amino}-8-fluoro-quinolin-2(1H)-one

Participants

Reaction Steps

Analogously to Example 10, the corresponding imine is produced starting from 250 g of 4-(3-chloro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-(trifluoromethyl)pentanal and 137 mg of 5-amino-8-fluoroquinolin-2(1H)-one. The title compound is obtained analogously to Example 3 by reaction of the imine that is formed with 1.4 ml of titanium tetrachloride solution (1 M in dichloromethane).
