%X Sa£¿etak Some 2,6-bis(hydroxymethyl)pyridinedicarbamates VII were synthesized by reaction of pyridinedimethanole (I) with carbamoylazoles II-VI (azole=imidazole, benzimidazole, pyrazole, 1,2,4-triazole, benzotriazole). It is confirmed that this reaction proceed via an intermolecular elimination-addition acyl transfer mechanism including in the first step the formation of an isocyanate. Carbamoylbenzotriazoles Vla-i were prepared by aminolysis of 1-benzot,riazole-' carboxylic acid chloride (VIII) obtained from benzotriazole and phosgene
