The novel 2-amino-3-carbethoxy-4- phenyl thiophene was synthesized by using a acetophenone and ethyl cyano acetate and the parent compound was reacted with chloroacetic acid and glacial acetic acid, the chloro compound was then substituted with different substituted primary and secondary amines to obtain a series of title compounds [SBJa 1-8]. All the new title compounds were characterized by spectral data and were screened for CNS depressant activity. In conclusion, it can be inferred that the electron donating groups on the phenyl ring at R of the title compounds influenced the CNS depressant activity
