    Abstract: The indole derivs. (I; R1 = pyrrolidino, piperidino, 4-hexamethyleneimino, morphorino, 4-hydroxypiperidino, 4-carbethoxy-piperidino, 1-piperaziny1; R2 = H, pyrrolidino, hexamethylene-imino, 4-hydroxypiperidino, morpholino, 1-piperazinyl; R3 = H, 6-methoxy; m= 1-2; R4 = H, Me, Ph, benzyl, alkoxypheny1), useful as hypotensive and antiarrhythmics, were prepd. by reaction of II(R = Cl, Br) and HNR5R6(R5, R6 = C1-6 alkyl). Thus, 51.2g II(R = Cl) was refluxed with 172g anhydrous piperazine in 500ml dioxane to give 46g 1-pheny1-2-piperazino-3-indole carbaldehyde.
