Claim 10:
11. A method of making the 2-alkoxy[4,3:6,3-terpyridine]-3-carbonitrile of claim 1, the method comprising:
adding a mixture of 3-acetylpyridine and 3-pyridine carboxaldehyde to a solution of a sodium alkoxide in an absolute alcohol with stirring to obtain a first reaction mixture;
adding malononitrile to the first reaction mixture to obtain a second reaction mixture;
irradiating the second reaction mixture followed by cooling to room temperature to obtain a solid precipitate;
purifying the solid precipitate by filtering and recrystallization using the absolute alcohol; and
obtaining the 2-alkoxy[4,3:6,3-terpyridine]-3-carbonitrile compound.
