Reaktionsschritte
(S)-3-methoxymethylamino-1-(2-thienyl)propan-1-ol obtained from Example 2 was dissolved in 10 ml of methanol with 8 mg of Raney-nickel. This resulting solution was provided in a glass autoclave and hydrogenated at 50° C. for 12 hours. Upon completion of hydrogenation, the reaction mixture was filtered, and the solvent was removed under reduced pressure to give a crystal compound (122 mg, 90.8% measured by HPLC assay, 95% ee). The crude product was further purified by re-crystallization in toluene to give a product with optical purity as high as 100% ee.
