A new synthetic route of (R)-(+)-N,N-Dimethyl-1-ferrocenylethylamine

31886-58-5, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,31886-58-5 ,(R)-(+)-N,N-Dimethyl-1-ferrocenylethylamine, other downstream synthetic routes, hurry up and to see

31886-58-5, A common heterocyclic compound, 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.”31886-58-5

Weigh I (5.0g, 19.4mmol) in 100mL reaction flask, dissolved with 50.0mL of ether, Sec-butyllithium (44.9 mL, 58.3 mmol, 1.3 M) was added dropwise to the reaction flask under nitrogen atmosphere, Stirred at room temperature for 2h, Weigh diphenylphosphine chloride (4.2mL, 23.3mmol) was added dropwise to the reaction flask, Warmed to reflux, 4h after the reaction is completed, The reaction solution was poured into water to quench, Extraction with ethyl acetate, drying, Ethyl acetate was removed by rotary evaporation, Purification by column chromatography on residue gave 7.5 g of the target compound VIII, Yield: 87.4%, yellow solid. Mass spectral analysis MALDI-TOF-MS m / z: 441 (M +).
