Usage
Description | Umeclidinium bromide is a long-acting muscarinic acetylcholine antagonist developed by GlaxoSmithKline and approved by the US FDA at the end of 2013 for use in combination with vilanterol, a b2 agonist, for the treatment of chronic obstructive pulmonary disease. Due to umeclidinium’s poor oral bioavailability, the drug is administrated by inhalation as dry powder. |
Uses | Umeclidinium Bromide is considered as a potentially long-acting antimuscarinic agent. |
Definition | ChEBI: A quaternary ammonium salt that is the bromide salt of umeclidinium. Used in combination with vilanterol for long-term maintenance treatment of airflow obstruction in patients with chronic obstructive pulmonary disease. |
Synthesis | Commercially available ethyl isonipecotate (278) was alkylated with 1-bromo-2-chloroethane in the presence of K2CO3 in acetone to give ethyl 1-(2-chloroethyl)piperidine-4-carboxylate (279). This material was then treated with lithium diisopropylamine (LDA) in THF to affect a transannular substitution reaction resulting in the cyclized quinuclidine 280 in 96% yield. Excess of phenyllithium was added to ester 280 in THF starting at low temperature then gradually warming to room temperature to give tertiary alcohol 281 in 61% yield. Amine 281 was finally alkylated with benzyl 2- bromoethyl ether (282) in MeCN/CHCl3 at elevated temperatures to afford umeclidinium bromide (XXXV) in 69% yield. |
