Procedure
A solution of 4,6-dichloro-pyrimidin-2-ylamine (5 g, 30 mmol) and acetyl chloride (4.7 g, 60 mmol) in acetic acid (200 mL) was stirred at 80° C. under nitrogen overnight. The solution was cooled to RT and water (150 mL) was added. The mixture was extracted with ethyl acetate (3×150 mL), and the combined organics were washed with brine, dried over sodium sulfate and concentrated to give N-(4,6-dichloro-pyrimidin-2-yl)-acetamide (5.0 g, 79% yield).
