Lè yo te reyaji avèk α-bromoesters, pyridine ap sibi yon reyaksyon Michael-renmen ak carbonyls yo enstore yo fòme piridin ki ranplase ak bromid pyridium. Reyaksyon an trete avèk asid amonyak nan 20-100 ° C kondisyon grav.

When reacted with α-bromoesters, pyridine will undergo a Michael-like reaction with the unsaturated carbonyls to form the substituted pyridine and pyridium bromide. The reaction is treated with ammonia acetate within 20-100°C mild conditions.
