Phenethylamine → HCID 21260532, compound

Participants

Reaction Steps

A mixture of 3-(4-methoxy-phenyl)-cyclohex-2-enone (prepared following the procedure described in CA:54-10947d) (2.0 g, 9.89 mmol), phenethylamine (1.20 g, 9.89 mmol), toluene (50 ml) and a catalytical amount of p-toluenesulfonic acid was refluxed in a Dean-Stark apparatus overnight. After removal of the solvent, the residue was dissolved in MeOH (30 ml) and sodium borohydride (excess) was added. After stirring for 1 h at RT, the solvent was evaporated, H2O was added to the residue. Extraction with CH2Cl2, drying of the organic layer over Na2SO4, evaporation of the solvent and flash-chromatography of the residue over SiO2 (Biotage-40, 90 g) eluting with CH2Cl2—MeOH 95:5 gave (RS)-[3-(4-methoxy-phenyl)-cyclohex-2-enyl]-phenethyl-amine (1.7 g, 56%, light yellow solid, MS: m/e=308.2 (M+H+)).
