N-(2,2-Dichloro-1-cyanoethenyl)carboxamides 1 are known to be highly reactive electrophilic reagents suitable for the synthesis of heterocyclic compounds. Two research groups headed by K. Matsumura and B. Drach began independently in the 1970s studying the cyclocondensation of these reagents with N-nucleophiles. It was found that the reaction of 1 with ammonia, high basicity amines, and hydrazine leads to the oxazole ring formation that has become a common method for the production of 5-amino-4-cyanooxazoles 2 (Scheme 1) [1-3]. A quite unusual cycloaddition of benzamidine to compounds 1 reported by Drach and co-workers was featured by the
