    摘要: A process of producing atracurium besylate that substantially reduces the level of impurities in the final product and avoids the repeated use of ether is provided. In accordance with such a process, N, N'-4,10-dioxa-3,11-dioxotridecylene-1,13-bis-tetrahydropapaverine (Compound 1), methyl benzenesulfonate and a catalytic amount of an insoluble base in a solvent are combined to form a reaction mixture that is maintained for a period of time sufficient for atracurium besylate formation. The reaction mixture is then filtered to remove the insoluble base and the atracuriurn besylate is precipitated.
