Claim 4:
5. A method of making the 6′-(3-bromophenyl)-2′-ethoxy-3,4′-bipyridine-3′-carbonitrile compound of claim 1, the method comprising:
adding a mixture of m-bromoacetophenone and 3-pyridinecarboxaldehyde to a solution of a sodium ethoxide in an absolute ethanol 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 ethanol; and
obtaining the 6′-(3-bromophenyl)-2′-ethoxy-3,4′-bipyridine-3′-carbonitrile compound.
