These common heterocyclic compound, 26487-67-2, name is 1-(2-Chloroethyl)azepane hydrochloride, 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. name: 1-(2-Chloroethyl)azepane hydrochloride
To a solution of 2,2-bis(4-hydroxyphenyl)methylenecyclohexane (23.3 mg, 83.1 mumol) in DMF (0.83 mL) at 0 ¡ãC was added 55percent sodium hydride (dispersion in paraffin liquid, 29.1 mg, 0.667 mmol). The reaction mixture was stirred for 30 min at 50 ¡ãC and then N-(2-chloroethyl)hexahydro-1H-azepine hydrochloride (54.5 mg, 0.275 mmol) was added in portions at room temperature. After the reaction mixture had been stirred for 4 h at 50 ¡ãC, saturated aqueous ammonium chloride was added at 0 ¡ãC. The mixture was extracted with dichloromethane and the organic layer was dried over sodium sulfate. After filtration of the mixture and evaporation of the solvent, the crude product was purified by thin layer chromatography on silica (eluant; ammoniacal chloroform/methanol = 15/1) to afford RID-F-S*16 (compound 14) (32.0 mg, 73percent) as a yellow oil
The synthetic route of 1-(2-Chloroethyl)azepane hydrochloride has been constantly updated, and we look forward to future research findings.
