Halocyclization of 2-alkynylthioanisoles by cupric halides: synthesis of 2-substituted 3-halobenzo[b]thiophenes
摘要:
Reaction of 2-alkynylthioanisoles 3 with 2 equiv of CuX2 (X=Br or Cl) in refluxing CH3CN for 2.5 h gave the 2-substituted 3-halobenzo[b]thiophenes 4 in good yields. (c) 2006 Elsevier Ltd. All rights reserved.
This application relates to novel compounds of formula I (and their pharmaceutically acceptable salts), as defined herein, processes and intermediates for their preparation, pharmaceutical formulations comprising the novel compounds of formula I, and the use of the compounds of formula I as thrombin inhibitors.
