    摘要: The present invention relates to a process for the manufacture of compounds of formula Ia or Ib and pharmaceutically acceptable additional salts thereof, wherein R is lower alkyl. The compounds of formula Ia or Ib are valuable intermediate products for the manufacture of compounds that are pharmaceutically active as adenosine A2a receptor antagonist or metabotropic Glutamate receptor 2 antagonist. Such compounds are important in the regulation of many aspects of cellular metabolism and in the modulation of different central nervous system activities.
