Versuchsvorschrift

Stir a mixture of 1-(2-Hydroxy-4-mercapto-3-propyl-phenyl)-ethanone (132 mg, 0.63 mmol), 3-(3-Iodomethyl-benzyl)-benzoic acid methyl ester (230 mg, 0.63 mmol), and cesium carbonate (410 mg, 1.26 mmol) in 2-butanone (6 ml) at room temperature under argon for 20 hours. Pour the mixture into water (60 ml) and extract with ethyl acetate (2×30 ml). Combine the organic extracts and wash with water, brine, then dry over sodium sulfate, filter and concentrate. Purify the crude product via silica chromatography eluting with 1:4 ethyl acetate:hexanes to give the title compound (240 mg, 85%). MS (m/z) 447 (M−H).
