实验步骤: N-phenylbenzamide (Structure II) is synthesized from aniline and benzoyl chloride using acetone as a reaction media and an aqueous solution of NaOH to neutralize the HCl generated. A 20 ml aqueous solution of NaOH (2.57 grams, 0.064 moles) and 6.0 grams (0.064 moles) of aniline are first added to a stirred 250 ml flask containing 75 ml of acetone. Benzoyl chloride (9.06 grams, 0.064 moles) is next added over a five minute period. This reaction mixture which now contains a white precipitate is stirred for 1.5 hours and then diluted with 50 ml of deionized water. This solution is next filtered and the filter cake obtained is sequentially washed with 50 ml of deionized water (two times) followed by 50 ml of methanol. The washed filter cake is recovered and DCS analysis of this product showed a sharp melting endotherm at 169° C. ##STR10## as a reaction media next filtered the filter cake obtained is sequentially washed with 50 ml of deionized water (two times) The washed filter cake is recovered at 169° C.

实验步骤: A reaction tube containing 1-iodo-2-nitrobenzene (124 mg, 0.5 mmol), N-phenylbenzamide (118 mg, 0.6 mmol), CuI (4.8 mg, 0.025 mmol), N-methylethylenediamine (4.4 μL, 0.05 mmol), potassium phosphate (212 mg, 1 mmol) in dry toluene (1.5 mL) was purged with dry argon for 3 min. After heating at 100° C. for 18 h, the iron powder (10 mol.-eq.) and glacial acetic acid (5 mL) are directly added. Then the reaction mixture is heated at reflux for 30 min. An additional 10 mol.-eq. of iron powder are added and the reaction mixture is heated at reflux for further 30 min. The solvents were removed under reduced pressure and the crude was extracted with ethyl acetate against saturated sodium bicarbonate solution. The organic phase was dried and the solvent was removed on a rotary evaporator. Then the residue was purified by preparative HPLC, affording the title compound as a solid (90 mg, 67% yield). was purged with dry argon for 3 min Then the reaction mixture is heated at reflux for 30 min the reaction mixture is heated at reflux for further 30 min The solvents were removed under reduced pressure the crude was extracted with ethyl acetate against saturated sodium bicarbonate solution The organic phase was dried the solvent was removed on a rotary evaporator Then the residue was purified by preparative HPLC
