The method of preparing 3- (tert-butoxycarbonyl amino) pyridine has been explored by many scholars in the past, and each has its own wonderful method. One method is to use 3-aminopyridine as the starting material to react with di-tert-butyl dicarbonate in a suitable solvent. This solvent is often selected from dichloromethane and tetrahydrofuran, both of which have good solubility and chemical stability. During the reaction, the system temperature should be controlled at a low temperature to room temperature, often starting in an ice bath and gradually rising to room temperature, so that the reaction can proceed steadily. Among them, the tert-butoxycarbonyl of di-tert-butyl dicarbonate can be nucleophilically substituted with the amino group of 3-aminopyridine to form 3- (tert-butoxycarbonyl amino) pyridine. < Br >
There is another method, using a derivative containing a pyridine ring as the starting material, first introducing an amino group through a series of reactions, and then interacting with di-tert-butyl dicarbonate by similar means to introduce tert-butoxycarbonyl. However, this path step is slightly complicated, and the reaction conditions of each step need to be carefully controlled to obtain a high-purity product.
During the preparation process, attention should be paid to the precise regulation of the reaction conditions. Temperature, proportion of reactants, reaction time, etc. are all key factors. If the temperature is too high, or side reactions occur frequently, the purity of the product will drop; if the temperature is too low, the reaction rate will be slow and time-consuming.
