実験手順: 2-Iodobenzoic acid (10.06 g, 40.56 mmol) was converted to 2-iodobenzoic chloride by reacting with oxalyl chloride (5.34 mL, 60.84 mmol) in methylene chloride (100 mL), initiated by a drop DMF. The solvent and excess oxalyl chloride were removed by rotary evaporation. To a 250 mL one neck round bottom flask was charged t-butanol with THF (50 mL) and then cooled to −78 C. A solution of n-butyl lithium in hexanes (2.5 M, 24.3 mL) was added, followed by the solution of 2-iodobenzoic chloride in THF (50 mL). The resulting reaction mixture was stirred at −78 C for 20 min and then at rt for 2 hours. The reaction was quenched by water and worked up. The product was purified by flash chromatography to afford the title compound as a white solid.

実験手順: To a solution of 0.149 g (0.35 mmol) of the product of Step G and 0.132 g (0.43 mmol) of t-butyl 2-iodobenzoate in 1 mL of anhydrous DMF was added 5 mg of bis(triphenylphosphine)palladium(II) chloride. The mixture was degassed, flushed with nitrogen, then magnetically stirred under a nitrogen atmosphere for 12 hours at 100° C. The reaction mixture was cooled to room temperature, then partitioned between EtOAc and water. The organic layer was extracted, separated, dried (MgSO4), filtered and evaporated. The residue was purified on a silica gel flash chromatography column eluted with 50% EtOAc-hexane. Evaporation of the purified fractions and drying in vacuo afforded 0.111 g (73%) of the title compound as an off-white amorphous solid.
