Reaction Steps

6-(2-(4-Iodophenyl)ethynyl)pyridine-3-ter-pyridine (Compound 94, Scheme 24) was prepared by stirring a mixture of Compound 93 (500 mg, 1.5 mmol), 2-Acetylpyridine (550 mg, 4.5 mmol), KOH 85% (360 mg, 4.5 mmol, and NH4OH 29% (7.5 ml, 6 mmol) in anhydrous ethyl alcohol (25 ml) and reflux for 14 hours. Thereafter the crude solid was collected by filtration, and washed with cold EtOH to produce the ter-pyridine Compound 94 as a brownish solid (65% yield).
