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 was stirred at 185° C. over night. The solution was diluted with 5N NaOH solution, the resulting mixture was stirred for 30 min. The aqueous layer was washed with diethylether, acidified at 0° C. with concentrated HCl until precipitation of the product was complete.
