    • 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.
    • 本发明涉及制备式Ia或Ib化合物及其药学上可接受的另外的盐的方法,其中R是低级烷基。 式Ia或Ib的化合物是制备作为腺苷A2a受体拮抗剂或代谢型谷氨酸受体2拮抗剂具有药学活性的化合物的有价值的中间产物。 这些化合物在调节细胞代谢的许多方面以及调节不同的中枢神经系统活性中是重要的。

    • The invention is concerned with a process for the preparation of a benzo[a]quinolizinone derivative of the formula ##STR1## by reacting a compound of the formula ##STR2## wherein X is halogen and Ph is phenyl, with carbon monoxide in the presence of a carbonylation catalyst and in the presence of (S)-3-ethoxypyrrolidine or a lower alkanol or water; where a lower alkyl ester of the 10-chloro-6,7-dihydro-4-oxo-3 -phenyl-4H-benzo[a]quinolizine-1-carboxylic acid has been obtained, converting this into the corresponding free acid; and, where the 10-chloro-6,7-dihydro-4-oxo-3-phenyl-4H-benzo[a]quinolizine-1-carboxylic acid has been obtained, reacting a reactive derivative thereof with (S)-3-ethoxypyrrolidine. The compound of formula I is useful for the treatment or prophylaxis of sleep disorders.
    • 本发明涉及制备式I的苯并[a]喹嗪酮衍生物的方法,其中式Ⅰ的化合物其中X为卤素且Ph为苯基的式Ⅰbb与一氧化碳在 在(S)-3-乙氧基吡咯烷或低级链烷醇或水的存在下,存在羰基化催化剂; 其中得到10-氯-6,7-二氢-4-氧代-3-苯基-4H-苯并[a]喹嗪-1-羧酸的低级烷基酯,将其转化为相应的游离酸; 并且其中已经获得了10-氯-6,7-二氢-4-氧代-3-苯基-4H-苯并[a]喹嗪-1-羧酸,使其反应性衍生物与(S)-3- 乙氧基吡咯烷。 式I化合物可用于治疗或预防睡眠障碍。
