Naftopidil (INN, marketed under the brand name Flivas) is a drug used in benign prostatic hyperplasia which acts as a selective α1-adrenergic receptor antagonist or alpha-1 blocker.[1]
Synthesis
[edit]
The reaction of 1-naphthol (1) with epichlorohydrin (2) in the presence of alkali gives the epoxide (3). Alkylation of the piperazine derivative (4) yields naftopidil.[2][3][4]
