Bromazine, sold under the brand names Ambodryl, Ambrodil, and Deserol among others, also known as bromodiphenhydramine, is an antihistamine and anticholinergic medication of the ethanolamine class.[1][2][3][4][5] It is an analogue of diphenhydramine with a bromine substitution on one of the phenyl rings.[1][2]
Synthesis
[edit]
Grignard reaction between phenylmagnesium bromide and para-bromobenzaldehyde [1122-91-4] (1) gives p-bromobenzhydrol [29334-16-5] (2). Halogenation with acetyl bromide in benzene solvent gives p-bromo-benzhydrylbromide [18066-89-2] (3). Finally, etherification with deanol completed the synthesis of Bromazine (4).
Side effects
[edit]Continuous and/or cumulative use of anticholinergic medications, including first-generation antihistamines, is associated with higher risk for cognitive decline and dementia in elderly people.[8][9]
