Reaction Steps

To a solution of 6-methoxy-5-(trifluoromethyl)pyrimidin-4-amine (N-3) (420 mg, 2.18 mmol) in 1,4-dioxane (10 mL), concentrated HCl (1.81 mL, 21.8 mmol) is added and the resulting mixture is stirred at 90° C. for 3 h. The mixture is allowed to cool to RT and then concentrated in vacuo to afford the product, 6-amino-5-(trifluoromethyl)pyrimidin-4-ol (N-4) as yellowish solid.
