The reaction mixture is dissolved with EtOAc and water, the aqueous layer separated off and extracted twice with EtOAc. The organic phases are washed with water and brine, dried (Na2SO4) and concentrated. Column chromatography (SiO2; EtOAc/hexane 1:1→3:1→4:1) gives the title compound: MS: [M+1]+=418; TLC(EtOAc): Rf=0.20.
