Ethyl orthoformate → HCID 178468256, compound

Participants

Reaction Steps

A mixture of 10 g of 5-aminotetrazole, 18 g of triethoxymethane and 200 ml of carbon tetrachloride was heated under nitrogen with stirring until distillate appeared. Then, a moderate rate of distillation was maintained for 6 hours with carbon tetrachloride being replaced in the reaction mixture as necessary. At this point, analysis of the crystals present showed complete conversion of aminotetrazole. The white crystals were then filtered from the hot solution and washed briefly with carbon tetrachloride to give a wet cake of 5-(ethoxymethyleneamino)tetrazole which was used immediately as is.
