Isovaleryl chloride → 2-amino-7-(2-dimethylamino-pyrimidin-5-yl)-[1,2,4]triazolo[1,5-a]pyridine-5-carboxylic acid N'-(3-methyl-butyryl)-hydrazide

Participants

Reaction Steps

The product of Step 2 (0.11 g, 0.35 mmol) was combined with isovaleryl chloride (0.04 mL, 0.35 mmol) and 5 mL of a 1:1 solution of THF/dioxane in a tube. The mixture was microwaved at 130° C. for five minutes. The reaction mixture was cooled, then the solid was collected by filtration to give 2-amino-7-(2-dimethylamino-pyrimidin-5-yl)-[1,2,4]triazolo[1,5-a]pyridine-5-carboxylic acid N′-(3-methyl-butyryl)-hydrazide. MS (APCI+): m/z 398.1.
