A Duloxetine intermediate. | [Synthesis]
General procedure for the synthesis of (S)-N,N-dimethyl-3-hydroxy-3-(2-thienyl)propylamine from N/A (Example 23): under argon protection, (R,R)-Cl2((R)-hexylBINAP)((R)-DAIPEN) (30.5 mg, 0.025 mmol), 2-propanol (100 ml), 1.0 M tert-butyl potassium oxychloride solution of 2-propanol (7.5 ml, 7.5 mmol) and 3-(N,N-dimethylamino)-1-(2-thienyl)-1-propanone (22.9 g, 0.125 mol) were added sequentially to a glass autoclave. After the reaction system was degassed several times and replaced with argon, hydrogen was introduced to a predetermined pressure to start the reaction. After stirring the reaction at 28°C for 6 hours, the reaction system was returned to normal temperature and pressure. The reaction solution was concentrated, heptane was added and the precipitated solid was filtered. The resulting solid was dried under reduced pressure to afford (S)-N,N-dimethyl-3-hydroxy-3-(2-thienyl)propylamine 18.5 g in 80.0% yield. The optical purity of the product was determined by chiral column HPLC, and the result showed that the optical purity was 99% ee. Note: (R)-DAIPEN is (R)-1-isopropyl-2,2-bis(p-methoxyphenyl)ethylenediamine, and xylBINAP is 2,2'-bis(bis-3,5-dimethylphosphinodiphenyl)-1,1'-binaphthyl. | [References]
