Versuchsvorschrift

Triethylamine (7 equivalents) is added to a solution of (3R,4S)-3-[(3S)-3-(4-fluorophenyl)-3-hydroxypropyl]-4-(4-hydroxyphenyl)-1-(4-iodophenyl)azetidin-2-one (i-6) (1.00 equivalent), N-prop-2-yn-1-ylmethanesulfonamide (i-5) (1.50 equivalents), tetrakistriphenylphosphine palladium(0) (0.15 equivalents) and copper(I) iodide (0.30 equivalents) in DMF (0.1 M concentration with respect to final product) under a nitrogen atmosphere and the resulting solution aged at room temperature. After completion of reaction, the volatiles are evaporated in vacuo and the crude residue can be purified by flash chromatography on silica gel to afford the title compound.
