Reaction Steps
Ethyl-2-(2-chloro-4-propionylphenoxy)acetate (4 g) was dissolved in methanol (40-50 ml). HCl (2 drops, conc) was added, followed by the dropwise addition over 5-10 minutes of bromine (2.62 g, 0.016 mole). After the bromine addition was complete the mixture was heated on a steam bath for 15-30 minutes allowing much of the solvent to evaporate. The residue was washed with cold water and the remaining solid recrystallized several times from hexane to give methyl 2-[2-chloro-4-(2-bromopropionyl)phenoxy]acetate (4.6 g, 90%, mp 63°-65° C.
