Procedure

A solution of 6-(5-methyl-2-furyl)pyrimidine-2,4,5-triamine (5.8 g, 30.1 mmol) in dioxane (116 mL) was treated with isoamyl nitrite (4.1 mL, 30.5 mmol), heated at 80° C. for 3.5 h, cooled to room temperature and the resulting precipitate was filtered, washed with dioxane (10 mL) and heptane (2×15 mL) then triturated with heptane and filtered to give the title compound (4.7 g, 77%) as a sandy solid.
