A. N-Methyl-N-phenyl benzamide (3). A single-necked (24/40 joint) 500 mL round-bottomed flask is equipped with a Teflon-coated magnetic stir bar (3 cm, oval-shaped). The flask is dried in an oven (105 °C) for 16 h. The flask is brought out of the oven, sealed immediately with a rubber septum, and allowed to cool to room temperature (23 °C) in a desiccator (Note 2). The flask is purged with argon by connecting to an argon manifold using a needle (18G), and via another needle (18G) to a gas outlet terminating in an oil bubbler. The atmosphere is maintained under a slight positive pressure of argon for the duration of the reaction (Note 3). The flask is then charged with triethylamine (6.5 mL, 47 mmol, 1.3 equiv) (Note 4) using a plastic syringe Et3N CH2Cl2, 0 °C to 23 °C 1
A. n-甲基-n -苯基苯酰胺(3)。单颈(24/40关节)500 mL圆底烧瓶配有特氟龙涂层的磁性搅拌棒(3厘米，椭圆形)。烧瓶在烤箱(105°C)中干燥16小时。烧瓶从烤箱中取出，立即用橡胶隔片密封，并允许在干燥器中冷却到室温(23°C)(注2)。烧瓶用氩气清洗，使用针(18G)连接到氩气歧管，并通过另一根针(18G)连接到气出口，终止于油起泡器。在反应过程中，气氛保持在氩气的轻微正压下(注3)。然后使用塑料注射器Et3N CH2Cl2, 0°C至23°C，向烧瓶注入三乙胺(6.5 mL, 47 mmol, 1.3当量)(注4)
