The synthetic route is as follows., Formula: C8H9IO2

3-[4-(3,4-Dimethoxyphenyl)-but-3-ynyl]-1,3-oxazolidin-2-one (34). Triethylamine (0.08 mL, 0.574 mmol) and Pd(PPh3)Cl2 (8.0 mg, 0.011 mmol) were added to a mixture of 3,4-dimethoxyphenyl iodide (33) (64 mg, 0.242 mmol) and alkyne 25 (34 mg, 0.245 mmol) in THF (3 mL) at room temperature. Then Cu(I)I (5 mg, 0.026 mmol) was added. The resulting mixture was stirred at room temperature for 4 h. The reaction was quenched with water (10 mL) and concentrated to remove the organic solvents. The residue was diluted with ethyl acetate (15 mL). The organic layer was separated and washed with brine (2.x.10 mL), dried over sodium sulfate and concentrated. The residue was purified by column chromatography on silica gel (25 g), eluting with EtOAc-hexanes (10-50percent) to afford the product 34 (54 mg) as solid in 80percent yield: mp 78-79° C. 1H NMR (300 MHz, CDCl3) delta 6.95 (dd, J=2.1 Hz, J=8.4 Hz, 1H), 6.88 (d, J=1.8 Hz, 1H), 6.76 (d, J=8.4 Hz, 1H), 4.32 (t, J=7.8 Hz, 2H), 3.86 (s, 3H), 3.85 (s, 3H), 3.73 (t, J=7.8 Hz, 2H), 3.51 (t, J=6.6 Hz, 2H), 2.67 (t, J=6.6 Hz, 2H); ESIMS m/z (rel intensity) 276.05 (MH+, 94), 298.05 (MNa+, 98). Anal. (C15H17NO4) C, H, N.
