Reaktionsschritte

Sodium hydroxide (17.6 g, 0.44 mol, ca. 2 eq.) was dissolved in water (240 g). Aqueous tri-methylamine (25%, 61.3 g, ca. 1.2 eq.) was added with cooling. The resulting mixture was cooled to 0° C. and ethyl (R)-4-chloro-3-hydroxybutyrate (content 100%, 36 g, 0.216 mol) was added dropwise within 3 h to the stirred reaction mixture. After one additional hour at 0° C. the reaction mixture was warmed to +20° C. and analyzed by HPLC
