Procedure

A mixture of 25 g of 5-aminotetrazole monohydrate and 356 g of triethoxymethane was heated under nitrogen with stirring at 100° C. for 4 hours during which time a distillate was collected. Then, 30 ml of cyclohexane was added and the mixture was cooled first to room temperature and then briefly with an ice-water bath. The white crystals which formed were separated by filtration and vacuum oven dried to give 5-(ethoxymethyleneamino)tetrazole.
