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
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]
