1-Azabicyclo(2.2.2)octan-3-one, hydrochloride (1:1)

Specifically, the 1-azabicyclooctan-3-one is reduced to (R)-3-quinuclidinol (3R-1-azabicyclooctan-3-ol), which is then reacted with (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline to form the final active pharmaceutical ingredient, (1S,3R)-solifenacin. 1-Azabicyclooctan-3-one hydrochloride (also known as 3-quinuclidinone hydrochloride) is a crucial, key intermediate employed to synthesize Solifenacin, an anti-muscarinic drug used to treat overactive bladder.
