摘要

Procedure to prepare dietries derived from 1-ethyl-2-aminomethyl pyrrolidine. 1-ethyl-2-aminometilpirrolidine racemica is dissolved in aqueous methanol and is treated with acid (-) - di-p-toluoil-l-tartaric with which crystallizes (-) - di-p-toluoil-l-tartrate of levo-1-ethyl-2-aminomethylprolroline and is isolated and the (-) - di-p-toluoil-l-tartrate dextro-1-ethyl-2- aminometilpirrolidin remains in mothers or is treated 1-ethyl-2-aminometilpir rolidine racemica with acid (-) - di-p-toluoil-l-tartaric in methanol with what crystallizes (-) - di-p-toluoil-l- dextro-1-ethyl-2-aminomethylprolrolineine tartrate and is isolated after which the addition of water to methanol's waters gives as a result the crystallization of (-) - di-p-toluoil-l-tartrate of levo-1 -etil-2-amcnometilpi rrolidina.se is used as an intermediate compound in the manufacture of pharmaceutical products.
