(S)-1-(4-Nitrophenyl)ethylamine hydrochloride Usage And Synthesis

Purification Methods

To ensure dryness, the hydrochloride (ca 175 g) is extracted with EtOH (3x100mL) and evaporated to dryness (any residual H2O increases the solubility in EtOH and lowers the yield). The hydrochloride residue is triturated with absolute EtOH and dried in vacuo. The product is further purified by refluxing with absolute EtOH (200 mL for 83g) for 1hour, and cool to 10o to give 76.6g of hydrochloride m 243-245o(dec). The free base is prepared by dissolving in N NaOH, extracting with CH2Cl2 (3 x 500mL), drying (Na2CO3), filtering, evaporating and distilling it. It has m 27o, b 119-120o/0.5mm (105-107o/0.5mm, 157-159o/9mm, d 1.1764, n 1.5688, [] ±17.7o (neat) [Perry et al. Synthesis 492 1977,ORD: Nerdel & Liebig Justus Liebigs Ann Chem 621 142 1959].
