実験手順
2-(3-{[(6-Chloro-2-fluoro-3-methoxy-benzyl)-((S)-1-dimethylaminomethyl-3,3-dimethyl-butyl)-amino]-methyl}-benzyl)-1,1-dioxo-1λ6-isothiazolidine-3-carboxylic acid ethyl ester (0.865 g, 1.4 mmol) was dissolved in tetrahydrofuran (5.6 mL). Water (5.6 mL) and lithium hydroxide (0.050 g, 2.07 mmol) and methanol (1.2 mL) were added. The reaction was stirred at room temperature for 2.5 hours after which the reaction was concentrated under reduced pressure. To the residue was added dichloromethane and aqueous hydrochloric acid (pH˜7) resulting in an emulsion. The reaction was then concentrated to dryness under reduced pressure. The crude material was purified by supercritical fluid chromatography into the corresponding Epimer 1 and Epimer 2 of 2-(3-{[(6-Chloro-2-fluoro-3-methoxy-benzyl)-((S)-1-dimethylaminomethyl-3,3-dimethyl-butyl)-amino]-methyl}-benzyl)-1,1-dioxo-1λ6-isothiazolidine-3-carboxylic acid (0.084 g (Epimer 1) and 0.089 g (Epimer 2), respectively, 99% (combined yield)).
