Synthesis

:500px

The displacement of the dimethylamino group in gramine (1) by the anion from 2-nitropropane gives 3-(2-methyl-2-nitropropyl)indole (2), which is reduced to the amine alpha,alpha-dimethyltryptamine (3). Separately, the reaction of 2-hydroxybenzonitrile (4) with epichlorohydrin gives the epoxide (5). Combination of the two intermediates (3) and (5) gives bucindolol.{{cite patent | inventor = Kreighbaum WE, Comer WT | title = 3-Indolyl-tertiary butylaminopropanols | country = US | number = 4234595 | gdate = 18 November 1980 | assign = Mead Johnson & Company | url = https://patents.google.com/patent/US4234595A/en?oq=us4234595 }}{{cite journal | vauthors = Kreighbaum WE, Matier WL, Dennis RD, Minielli JL, Deitchman D, Perhach JL, Comer WT | title = Antihypertensive indole derivatives of phenoxypropanolamines with beta-adrenergic receptor antagonist and vasodilating activity | journal = Journal of Medicinal Chemistry | volume = 23 | issue = 3 | pages = 285–289 | date = March 1980 | pmid = 6102605 | doi = 10.1021/jm00177a015 }}
