Методика

After the reaction liquid had been adjusted to a pH of 13 by the addition of 5 N aqueous solution of sodium hydroxide, N-benzyl-3-aminopiperidine was extracted with 1 L of toluene, and was then further extracted from the aqueous phase with 1 L of toluene. After the solvent had been distilled under reduced pressure away from a combination of the organic phases thus obtained, (R)—N-benzyl-3-aminopiperidine was purified by distillation. Thus, 17.7 g of (R)—N-benzyl-3-aminopiperidine were obtained in the form of colorless oil.
