Imiloxan is a drug which is used in scientific research. It acts as a selective antagonist for the α_2B adrenergic receptor,^[1] and has been useful for distinguishing the actions of the different α₂ adrenergic subtypes.^[2]^[3]

Synthesis

The imidazole portion of imiloxan is prepared by the reaction of an imidate with the diethyl acetal of aminoacetaldehyde. N-Alkylation of the imidazole with ethyl iodide gives imiloxan.
