HCID 53957258Ethyl 4-[4-(4-bromophenoxy)phenyl]-4-oxobut-2-enoate

Procedure

The procedure in Example 17(1) was followed, except that 6.92 g 3-[4-(4-bromophenoxy)benzoyl]acrylic acid were used in place of 3-[4-(4-methylphenoxy)benzoyl]acrylic acid, to give 6.00 g of ethyl 3-[4-(4-bromophenoxy)benzoyl]acrylate in the form of an oil.
