with silica gel in toluene;Reflux;Concentration;Reagent/catalyst;

Steps:

3 Example 3

Into a 250 mL four-necked flask, 150 mL of toluene, p-methoxybenzoic acid (34 g, 0.2 mol), α-pyrrolidone (17 g, 0.2 mol), silica (6 g, 10 mmol) were refluxed, and methanol was distilled off. . Methanol was evaporated and cooled to 15°C to precipitate a solid. Filter to obtain a solid cake. Dissolve with 95% ethanol, decolorize the activated carbon, filter it while hot, crystallization after cold, filter and filter cake to obtain dried aniracetam finished product 39.5g. (Yield is 91%)
