Versuchsvorschrift

A solution of 8.60 g of the product of Step C and 21.30 g of ammonium acetate in MeOH was heated in a sealed system at 100° C. for 24 h. The solution was cooled to ambient temperature and concentrated to leave an oil that was partitioned between EtOAc and water. The aqueous layer was acidified to pH 5 with concentrated HCl and then extracted with EtOAc. The combined organic layers were washed with sat. sodium chloride, dried over sodium sulfate, filtered, and concentrated to provide 2,6-di-tert-butyl-2H,7H-[1,2,4]triazolo[4,3-a]pyrazine-3,8-dione as a white solid. MS (M+H+)=265.3.
