To prepare 3- (1-methylpyrrolidine-2-yl) pyridine sulfate (2:1), the method is as follows:
First take an appropriate amount of 3- (1-methylpyrrolidine-2-yl) pyridine and place it in a clean reaction vessel. This pyridine derivative needs to be carefully purified to ensure that there are few impurities, so as not to disturb the subsequent reaction.
Prepare a container and measure an appropriate amount of sulfuric acid. The concentration and purity of sulfuric acid need to be precisely controlled. Improper concentration will easily cause reaction skew, and insufficient purity will also introduce impurities.
Slowly add sulfuric acid dropwise to a reaction vessel containing 3- (1-methylpyrrolidine-2-yl) pyridine, the dropwise rate should be slow, and the stirring should be continuous. Due to the reaction or exothermic, too fast dropwise addition may cause the temperature to rise sharply, triggering side reactions. Stirring can make the two fully contact and promote the uniform progress of the reaction.
Add it dropwise, and continue to stir to make the reaction fully. The reaction time should be determined according to the specific situation, or the reaction progress can be monitored by means of instruments, and the reaction should reach the desired level.
After the reaction is completed, the properties of the product can be seen, and the appropriate separation and purification method can be selected. If the product is solid, the method of Select a suitable solvent, heat to dissolve the product, filter while hot to remove impurities, and then cool down to crystallize the product. After filtration, washing, and drying, pure 3- (1-methylpyrrolidine-2-yl) pyridine sulfate (2:1) can be obtained. If the product is a liquid, it can be purified by distillation, extraction, etc. to achieve the required purity standard. The whole process must be carefully operated and attention to detail to obtain a satisfactory product.
