Antrafenine (Stakane) is a phenylpiperazine derivative drug invented in 1979.[1] It acts as an analgesic and anti-inflammatory drug with similar efficacy to naproxen,[2] but is not widely used as it has largely been replaced by newer drugs.

Synthesis[edit]

Thieme Synthesis:[1] Patents:[3][4][5]

Method E: The reaction between 2-[4-[3-(trifluoromethyl)phenyl]-1-piperazinyl]ethanol [40004-29-3] (1) and Isatoic anhydride [118-48-9] (2) goes on to give 4-(3-(Trifluoromethyl)phenyl)piperazine-1-ethyl 2-aminobenzoate [51941-08-3] (3).

Method G: Alkylation with 4-chloro-7-(trifluoromethyl)quinoline [346-55-4] (4) completed the synthesis of antrafenine (5).

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
