The RM was diluted with EtOAc and washed with water, with brine, dried over Na2SO4, filtered and evaporated. The residue The residue was absorbed on silica gel and purified by flash chromatography (CH2Cl2/MeOH 0% to 8%). The fractions containing product were evaporated together to give the title compound as an off-white solid.
