Versuchsvorschrift
To (E)-methyl 3-(3,5-dichlorophenyl)acrylate (step 1) (2 g, 8.66 mmol) in THF (35 ml) was added 2M NaOH (12.98 ml, 26.0 mmol) and the reaction mixture was stirred at RT overnight. The solvent was removed under reduced pressure and the residue was dissolved in water and washed with EtOAc. The aqueous portion was acidified to pH 4 using 1M HCl and extracted with DCM. The organic portion was dried using a phase separating column and the solvent removed under reduced pressure to afford the title compound as a white solid;
