Triethylamine (0.07 mL, 0.502 mmol) was added to a stirred solution of 4-[(2S,3R)-3-[(3S)-3-(4-fluorophenyl)-3-hydroxypropyl]-1-(4-iodophenyl)-4-oxoazetidin-2-yl]phenyl methyl β-D-glucopyranosiduronate (i-7) (0.050 g, 0.071 mmol), N-prop-2-yn-1-ylmethanesulfonamide (i-5) (0.014 g, 0.105 mmol), tetrakistriphenylphosphine palladium(0) (0.012 g, 0.010 mmol) and copper iodide (0.005 g, 0.026 mmol) in DMF (0.5 mL) under a nitrogen atmosphere and the resulting solution aged at room temperature for 18 h. The volatiles were evaporated in vacuo and the crude residue purified by flash chromatography on silica gel (gradient elution; 0-25% methanol/methylene chloride as eluent) to afford the title compound; m/z (ES) 713 (MH+), 505.
