Reaction Steps
A solution of 5.00 g 3-amino-5-ethyl-1,2,4-triazole and 15.00 g diethyl phenylmalonate in 18 ml N,N-dibutylbutan-1-amine is stirred at 185° C. over night. The solution is diluted with 5N NaOH solution, the resulting mixture is stirred for 30 min. The aqueous layer is washed with diethylether, acidified at 0° C. with concentrated HCl until precipition of the product is complete. The precipitate is collected by filtration to yield the product, which is used without further purification.
