    摘要: The present invention relates to a process for preparing tolterodine and the L-tartrate thereof. The preparation consists of the following steps: A) ammonolysis reaction between diisopropylamine and compound 2 (3,4-dihydro-6-methyl-4-phenyl-2H-benzopyran-2-one) activated by an activator to afford the amide 3; B) reduction of the amide by a reductant to give compound 1, i.e., racemic tolterodine free base; C) Resolution of the tolterodine free base to afford tolterodine L-tartrate. The present route is very short and suitable for industrial production.

    摘要: The chiral compound S-5-substituted-N-2′-(thienyl-2-yl-)ethyl-tetralin-2-amine or its chiral acid salts and preparation method thereof are disclosed, and the method for preparing Rotigotine by using the chiral compound is also disclosed. Racemic 5-substituted-N-2′-(thien-2-yl-)ethyl-tetralin-2-amine (compound 1) is resolved by using a conventional chiral acid to obtain an optically pure chiral acid salt of S-5-substituted-N-2′-(thien-2-yl-)ethyl-tetralin-2-amine, which is then dissociated to obtain S-5-substituted-N-2′-(thien-2-yl-)ethyl-tetralin-2-amine (compound 2). The compound 2 or chiral acid salt thereof is alkylated and deprotected to produce rotigotine (compound 5).
