Reaction Steps

Dissolve 2,3,4-triaminopyridine (2.5 mmol) in water (20 mL). Add NaHCO3 (0.63 g, 7.5 mmol), dioxane (10 mL), and 2-bromo-1-(3-trifluoromethyl-pyridin-2-yl)-ethanone hydrobromide (0.5 g) and stir at 100° C. for 2 hours. Cool the mixture and extract with EtOAc (4×10 mL). Wash the combined organic extracts with brine and dry over Na2SO4. Purify the residue by preparative HPLC to give the title compound.
