(3RS,1SR)-3-Bromo-3-(1-phenylpropyl)chroman-2,4-dione

The title compound, C18H15BrO3, was obtained by bromination of phenprocoumone with N-bromo­succin­imide. The X-ray structure confirms an earlier proposal concerning the regioselectivity of the reaction to introduce the Br atom at the 3-position.
