    Abstract: Isoquinolines I(R1 = amino group -N(R4)(R5); R4, R5 = alky1 and make 5-8 membered cycle with N; R2 = halogen, OH, nitro, amino, substituted amino, mono- or di-substituted pheny1, pyridy1 or thieny1; R3 = H, OH, halogen, C1-6 alky1, alkoxy, NO2, amino, ethylenedioxy; m = 1,2), exhibiting effective activities for melancholia, were prepd. by reacting compds. II (X = H, carboxy1; Y = cl, Br) with amines (III). Thus, 3-chloro-1-pheny1-isoquinoline-4-carboxylic acid was heated to 150oC in N-methy1-piperazine and maintained for 6 hr to give 3-N-methy1piperazino-1-pheny1-isoquinoline.
