(Chemical Equation Presented) 2-Chloro-4,6-diarylnicotinonitrile 1 was reacted with ethyl 2-mercaptoacetate 2 to furnish ethyl 2-(3-cyano-4,6- diarylpyridin-2-ylthio)acetate 3 as intermediates. These intermediates were cyclized by Thorpe-Zeigler cyclizati

2-Aryl-3-aroyl-1,1-dicyanopropanes and 2-aryl-3-aroyl-1-bromo-1,1-dicyanopropanes were synthesized from chalcones and malononitrile and were converted into 4,6-diaryl-2-bromo-3-cyanopyridines and 3-cyano-2(1H)-pyridinethiones.The 2-aryl-3-aroyl-1-bromo-1,1-dicyanopropanes proved convenient intermediates for the production of the corresponding cyclopropanes and other compounds.By their reaction with urea a new method was developed for the production of substituted 3-cyano-2(1H)-pyridinethiones.The 2-bromo-3-cyanopyridines contain a mobile bromine atom readily exchanged for the various nucleophilic residues of alcohols and amines and for iodide, and cyano and thiocyanato groups.The 3-cyano-2(1H)-pyridinethiones were used in the synthesis of 3-aminothienopyridines through the isolated 2-Z-methylthio-3-cyanopyridines.
