Reaction Conditions

Reaction Steps

To a chloroform (20 mL) solution of methyl 3-(4-chlorophenyl)-3-oxopropanoate (1.0 g), bromine (0.12 mL) was added, and the resultant was stirred at 70° C. for 1 hour under sealed conditions. Then, bromine (0.12 mL) was further added thereto, and the resultant was further stirred at 70° C. for 1 hour under sealed conditions. The reaction solution was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (OH-type silica gel; hexane/ethyl acetate-gradient elution=100/0→75/25) to obtain the title compound (0.44 g) as a pale yellow oil.
