charged with 23 (113 mg,0.585 mmol) and 1,2,4,5-tetraiodobenzene
(81 mg,0.139 mmol),evacuated,and filled with argon.
Dry piperidine (15 mL) was added from a syringe,and the
solution was degassed by three freeze-pump-thaw cycles.
Then,Pd(PPh3)4 (17 mg,2.5 mol %) was added from a tip tube,
and the reaction mixture was stirred for 4 days at 55 °C.More
Pd(PPh3)4 (17 mg,2.5 mol %) was added from a tip tube,and
the reaction was continued for 4 more days.Then,NaOH/
EDTA (0.1 M in water,5 mL) was added,and the mixture was
stirred for 10 min.The phases were separated,and the
aqueous layer was extracted with toluene (3 \2 5 mL).The
organic layers were combined,and the solvents were evaporated
under reduced pressure.The crude product was dissolved
in chloroform and dried over Na2SO4 before the solvent was
evaporated under vacuum.The solid was chromatographed by
PTLC (alumina,chloroform),and 6 was obtained as small
needles after crystallization from chloroform:55 mg (47%);
