Abstract:Pipecuronium bromide(1)was synthesized in overall yield of 19.3% in several steps and its structure was characterized with 1H NMR and MS spectra. In the synthesis process of the key intermediate 2β,16β-bis -(4-methyl-piperazinyl)-3α-hydroxy-17-keto-5α-androst steranes(5),the bromination was combined with the ring-opening addition in one step thus effectively reduced the production costs. This improved process is simple and conducive to industrial production. |
Key words:pipecuronium bromide;synthesis;improved |
