Procedure

A mixture of 14 g of 3-amino-1,2,4-triazole, 0.17 mol of the ester from example 1 and 50 ml of tributylamine (50 ml) was stirred at 180° C. for approximately 6 hours. A solution of 21 g of NaOH in 200 ml of water was added at approximately 700 and the mixture was stirred for a further 30 min. The organic phase was separated and the aqueous phase was extracted with diethyl ether. The product precipitated from the aqueous phase after acidification with concentrated hydrochloric acid. 28 g of the title compound were obtained by filtration.
