Aldehydes condense with DISN to give 2-alkylimidazoles, but in low yield (73USP37099(X)). A related reaction with ketones produces 2,2-dialkyl-4,5-dicyano-2//-imidazoles. When one alkyl group is methyl and the other is a...

Hydrolysis of 4,5-dicyanoimidazole yields 4-amino-5-imidazole-car-boxamide which is converted by hypobromite into 4-amino-5-imidazole carbonitrile.444 Hydrolysis of the dicyano compound with aqueous alkali yields the corresponding 4,5-dicarboxylic acid.156 Reduction of the dicyanide with lithium aluminum hydride occurs with greater ease when the imino nitrogen carries a methyl substituent.156...
