Reaction Steps
A solution of 10 g 1,2,4-triazol-3-amine and 33.7 g diethyl phenylmalonate in N,N-dibutylbutan-1-amine is stirred at 185° C. over night. The solution is diluted with 10% w/w NaOH solution, the resulting mixture is stirred for 30 min and the organic phase is separated. The aqueous layer is extracted with diethylether, acidified with concentrated HCl until precipition of the product is complete and the precipitate collected by filtration to yield the product, which is used without further purification.
