Reaktionsschritte

To 100 g of 2-(4-methoxyphenyl)ethylamine in 500 mL of chloroform was slowly added 100 mL of triethylamine acetic anhydride (72 g), and this was stirred at 20° C. for 40 minutes. The mixture was then extracted twice with a dilute aqueous solution of HCl (0.4 N, 400 mL) followed by a saturated aqueous solution of NaHCO3 (2×400 mL). The solvent was removed by rotary evaporation, and the residue was dried in a vacuum oven (45° C.), resulting in an off-white powder, N-[2-(4-methoxyphenyl)ethyl]acetamide (120 g, 93.9% yield). 1HNMR (DMSO-d6) spectrum was consistent with the desired product.
