Versuchsvorschrift
The process of Example 3 is repeated using o-chlorophenylacetaldehyde to prepare ethyl 2-isopropyl-4-(o-chlorophenyl)-3-butenoate, which is hydrolyzed (potassium hydroxide-water/methanol) to the acid, 2-isopropyl-4-(o-chlorophenyl)-3-butenoic acid. The acid is reacted with m-phenoxybenzyl bromide as in Example 1 to yield m-phenoxybenzyl 2-isopropyl-4-(o-chlorophenyl)-3-butenoate. MS m/e 420 (M+).
