The invention discloses 1,2,5,6-tetrahydro-4H-pyrrolo-(3,2,1-ij)quinolin-2-ones having pharmacological activity in animals and useful as CNS depressant agents. The compounds may be prepared by treating a haloacetyl derivative of 1,2,3,4-tetrahydroquinoline with a Friedel-Crafts catalyst. The haloacetyl derivative of 1,2,3,4-tetrahydroquinoline may be prepared by reacting 1,2,3,4-tetrahydroquinoline with a haloacetyl halide at a mole ratio of 2:1 in the presence of an inert, organic solvent.
该发明揭示了在动物中具有药理活性并可用作中枢神经系统抑制剂的1,2,5,6-四氢-4H-吡咯啉-(3,2,1-ij)喹啉-2-酮。这些化合物可通过用Friedel-Crafts催化剂处理1,2,3,4-四氢喹啉的卤乙酰衍生物来制备。1,2,3,4-四氢喹啉的卤乙酰衍生物可通过在惰性有机溶剂存在下将1,2,3,4-四氢喹啉与卤乙酰卤在2:1的摩尔比下反应来制备。
