Reaction Steps

tert-Butyl 4-[5-(trifluoromethyl)pyridin-3-yl]piperazine-1-carboxylate (0.24 g, 0.25 mmol) was treated with a 4.0 M solution of HCl in 1,4-dioxane (7 mL) at room temperature for 1 h and concentrated. The residue was used for next step without further purification. MS calculated for C10H12F3N3: (M+H) 232; found 232.1.
