Versuchsvorschrift

Add K2CO3 (1.48 g, 10.7 mmol) to a solution of 1-(3-chloro-2,4-dihydroxy-phenyl)ethanone (2.00 g, 10.7 mmol) and 1,4-bis(bromomethyl)benzene (2.83 g, 10.7 mmol) in acetone (100 mL). Cool and work up with a 10% HCl solution and EtOAc. Triturate in acetone to remove insoluable material. Dry, filter, and concentrate. Purify the residue by flash chromatography on silica gel (731 mg, 18%): MS (esi negative) m/z 368.9 (rel intensity) (M−H, 55%), 367.0 (45%).
