==Synthesis== thumb|center|500px|Synthesis: Patent: Ex 1: The α-keto bromination of propiophenone [93-55-0] (1) gives 2-bromopropiophenone [2114-00-3] (2). Displacement of the halogen and hence amination with piperidine [110-89-4] gave alpha-Piperidinopropiophenone, CID:458526 (3). and addition of phenyl Grignard reagent to give the benzhydrol product, and hence Dihepanol (4).
