WHITE FINE CRYSTALLINE POWDER | [Application]
Acetamidine hydrochloride can be used as an organic synthesis reactant for the preparation of other compounds such as 2-aminopyridine derivatives. Nucleophilic substitution and hydrolysis of 2-fluoropyridine and acetamidine hydrochloride can be used to synthesise 2-aminopyridine derivatives under catalyst-free conditions[1]. This amination reaction has the advantages of high yield, high chemoselectivity and wide substrate adaptability using acetamidine hydrochloride as the ammonia source. In addition, an efficient heterogeneous copper-catalysed cascade reaction of aryl iodides with acetamidine hydrochloride produces primary amines[2]. | [General Description]
Acetamidine hydrochloride is an amidine salt and its conversion to 2,4,6-trimethyl-sym-triazine has been studied. | [Purification Methods]
The hydrochlorde can be recrystallised from small volumes of EtOH. Alternatively it is dissolved in EtOH, filtered, Et2O is added; filter the crystalline salt off under N2 and dry it in a vacuum desiccator over H2SO4. The salt is deliquescent and should be stored in a tightly stoppered container. Its solubility in H2O is 10% at room temperature and it is soluble in Me2CO. The free base reacts strongly alkaline in H2O. It has max 224nm ( 4000) in H2O. The picrate has m 252o (sintering at ~245o).
