Electric Literature of 1836-62-0, A common heterocyclic compound, 1836-62-0, name is 2-(2-Methoxyphenoxy)ethylamine, molecular formula is C9H13NO2, 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.
General procedure: Et3N (4.3 mmol) and 97% EtOCOCl (4.3 mmol) in dry CHCl3(25 mL) were added to a solution of the suitable carboxylic acid 24a,24b or 25 (4.3 mmol) at 0 C. After 30 min at 0 C under stirring asolution of the suitable amine (2-phenoxyethanamine, 2-(2-methoxyphenoxy)ethanamine [37], 2-(2,6-dimethoxyphenoxy)ethanamine [38], or 1-(2-methoxyphenyl)piperazine) (4.3 mmol)in dry CHCl3 (10 mL) was added and the reaction mixture was left atroom temperature for 3 h. The solution was washed with 2 N HCl and 2 N NaOH. The organic layer was dried over Na2SO4. After evaporation of the solvent the residue was purified by column chromatography eluting with cyclohexane/EtOAc (7:3).
The synthetic route of 1836-62-0 has been constantly updated, and we look forward to future research findings.
