A common heterocyclic compound, 26487-67-2, name is 1-(2-Chloroethyl)azepane hydrochloride, molecular formula is C8H17Cl2N, its 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. 26487-67-2.
General procedure: A mixture of riccardin D, alkyl chloride hydrochloride and potassium carbonate in acetone was stirred under reflux for 24h. The insoluble material was then filtered off and the filtrate was concentrated to provide the residue that was purified by flash column chromatography, eluting with a gradient mixture of MeOH/ EtOAc/aqueous ammonia (93:5:2 to 80:18:2, V/V), to yield the pure product (compounds 17a-17f and 18a-18f) as a solid in good yield.
The synthetic route of 1-(2-Chloroethyl)azepane hydrochloride has been constantly updated, and we look forward to future research findings.
