Reaction Steps
A suspension of 1,3,5-trimethylpyrazol-4-amine (1 g, 7.99 mmol), potassium acetate (0.862 g, 8.79 mmol) and acetic anhydride (0.889 mL, 7.99 mmol) in EtOAc (25 mL) was stirred at 25° C. overnight. Silica gel was added and the mixture was concentrated. The crude product was purified by flash chromatography on silica gel eluting with 0 to 5% MeOH in DCM. The solvent was evaporated to dryness to afford N-(1,3,5-trimethylpyrazol-4-yl)acetamide (1.390 g, 104%) as a off-white solid. Mass spectrum: MH+ 168
