実験手順
(2S,3R)-1-(Dimethylamino)-3-(3-methoxyphenyl)-2-methylpentan-3-ol (754.1 g, 3 mol, ee 95%) were dissolved in acetone (5 L) in a 10 L double jacket vessel equipped with an electrical impeller stirrer, a gas transition line, Pt100 temperature measuring equipment and an oil based cooling/heating system. Hydrogen chloride (110 g, 3.0 mol) was transferred within 15 minutes at a temperature of 15° C. through the reaction mixture. The reaction mixture was cooled to 0° C. to 5° C. and after 24 hours at that temperature siphoned off. The product was stored at 40° C. and 10 mbar for 14 hours in a drying oven. (2S,3R)-1-(Dimethylamino)-3-(3-methoxyphenyl)-2-methylpentan-3-ol hydrochloride was obtained as a colorless solid (722.3 g, 83.7%, ee 100%).
