Versuchsvorschrift

To a solution of triethylamine (2.9 g, 14.4 mmol) and 5-methoxy-2-methylaniline (1.0 g, 7.2 mmol) in DCM (30 mL) at 0° C., was added acetyl chloride (0.57 g, 7.2 mmol) dropwise. The mixture was stirred at room temperature for 1 hour. The reaction was quenched with saturated ammonium chloride aqueous solution, and extracted with DCM. The organic layer was dried over Na2SO4 and concentrated to give N-(5-methoxy-2-methylphenyl)acetamide as needle-shaped crystals. The crude product was used in the next step without further purification.
