Vecuronium bromide position isomer impurity preparation method

The invention discloses a vecuronium bromide position isomer impurity preparation method, and relates to the technical field of synthesis and preparation of chemical substances. By taking androstane-2-alkene-17-ketone as a raw material, a vecuronium bromide position isomer impurity is obtained through oxidization, ring opening, quaternary amination, bromination, substitution, reduction and acetylation reaction. The vecuronium bromide position isomer impurity prepared through the preparation method is high in purity and can be used as a contrast.

Novel method for preparing rocuronium bromide

The invention relates to a novel method for preparing rocuronium bromide 1-[17beta-acetoxyl-3alpha-hydroxyl-2beta-(4-morpholinyl)-androstane-16beta-yl]-1-(2-propenyl) pyrrole bromide, the problem of chemoselectivity of pyrrolidine open epoxy in an original line is solved, generation of byproducts is avoided, reaction yield is greatly improved, the production cost is reduced, column chromatography separation is avoided, and aftertreatment purification is implemented easily.
