Actually, the reaction of the 1-azaallyl anion having a pyridine ring instead of the isoxazole ring with 2-cyanopyrazine did not produce the corresponding vinyl amidine in a practical yield (<10%). Although the reaction of a vinyl amidine involving other aromatic rings with an acetal was not examined, the reaction would proceed. The detailed results will be published elsewhere.
