The invention provides a compound of formula I, wherein X, Z, R1 to R10, R15, R16, m, n, r and t are as defined in claim 1, or a pharmaceutically acceptable salt or ester thereof, useful as an alpha-2 antagonist. The compounds of formula I can be used for the treatment of diseases or conditions where antagonists of alpha-2 adrenoceptors are indicated to be effective.
A number of 1-substituted 3,4-dihydro-9H-β-carboline derivatives (4) with high purity and yields have been synthesized by treating of tryptamine (1) with carboxylicacids (2) in polyphosphoric acid. 3,4-Dihydro-9Η-β-carbolines (4) were successfully transformed to 1,2,3,4-tetrahydro-9H-β-carbolines (5) and 9H-β-carbolines (6).
