What are 1H-imidazole-1-propylamine synthesis methods?

The synthesis method of 1H-imidazole-1-propylamine is an important topic in the field of organic synthesis. In the past, many researchers have made great efforts to achieve this.

One method is to use imidazole and halopropylamine as raw materials, add a base as a catalyst in a suitable solvent, and make it undergo nucleophilic substitution reaction. For example, potassium iodide is used as a catalyst, potassium carbonate is a base, in acetonitrile solvent, imidazole interacts with 3-chloropropylamine hydrochloride, and after heating and reflux for several hours, the product can be obtained. In this process, the halogen atom of halopropylamine has high activity, and the nitrogen atom of imidazole has good nucleophilicity. Only when the two are compatible can this reaction be achieved.

There are also 1- (3-hydroxypropyl) imidazole as the starting material, which is converted into 1H-imidazole-1-propylamine by the amination reagent. If the hydroxyl group is first converted into a chlorine atom by dichlorosulfoxide, and then co-heated with the alcohol solution of ammonia, the nucleophilicity of ammonia attacks the chlorine atom and replaces it to obtain the target product. In this path, 1 - (3-hydroxypropyl) imidazole is easy to prepare, and the subsequent conversion steps are also relatively clear.

In addition, 1 - (3-cyanopropyl) imidazole is synthesized from nitrile compounds, and then the cyanyl group is converted into an amino group by reduction reaction. If Raney nickel is used as the catalyst and hydrogen is used as the reducing agent, 1 - (3-cyanopropyl) imidazole is reduced to 1H-imidazole-1-propylamine at a suitable temperature and pressure. In this way, the reduction of cyanyl groups needs to be controlled under suitable conditions to achieve the ideal yield. < Br >
All these synthesis methods have their own advantages and disadvantages. Fang family needs to weigh the choice according to many factors such as the availability of raw materials, the difficulty of reaction conditions, and the high or low yield, in order to find the best synthesis path.
