Procedure

Potassium hydroxide (1.27 g) was dissolved in 100 ml of ethanol and 5 g of 3-(1H-tetrazol-5-yl)oxanilic acid was added to the solution, followed by stirring at room temperature for 4 hours. Crystals separated out from the reaction solution were filtered off, washed with 50% aqueous solution of ethanol and dried under reduced pressure at 40° C. in the presence of phosphorous pentoxide to obtain 4.65 g of the objective potassium 3-(1H-tetrazol-5-yl)oxanilate (yield 85%). Decomposition point: not less than 300° C.
