Application of 66247-84-5,Some common heterocyclic compound, 66247-84-5, name is (1H-Imidazol-4-yl)methanamine hydrochloride, molecular formula is C4H8ClN3, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

General procedure: To a solutionof the corresponding aldehyde (1.2 eq.; unless stated otherwise) in DMF (2 inL per 0.3 mmol of aldehyde; unless stated otherwise) was added the corresponding amine (2.5 eq.; unless stated otherwise) and the resulting solution was stirred at 25 C to form the corresponding inline. Then, the corresponding isocyano(tosyl)methyl)arene reagent (1 eq.; unless stated otherwise) and K2CO3 (1.5 eq.; unless stated otherwise*) were added and the reaction mixture was stirred at 25 C (unless stated otherwise). The reaction was stopped after the time indicated for each particular reaction. The reaction progress was monitored by TLC. (0083) A saturated aqueous solution of NH4CI (10 mL per 1 mmol of aldehyde) was added to the reaction mixture, which was then extracted with EtOAc (2 x 30 mL per 1 mmol of aldehyde). The combined organic extracts were washed with H2O (2 x 25 mL per 1 mmol of aldehyde), dried over MgSCC, filtered, and the solvent was evaporated in vacuo to provide the crude product. The residue obtained after the workup was purified using column chromatography or preparative TLC (unless stated otherwise). (0084) * note: in cases when the amine was used as HC1 salt, 4 eq. of K2CO3 were used

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route (1H-Imidazol-4-yl)methanamine hydrochloride, its application will become more common.
