Participants

Reactant 3

HCID 3283Diethyl Ether

HCID 128050991-[2-(3-Bromophenyl)propyl]-2-(cyclohexylmethyl)piperidine

HCID 178418339Butyllithium

Product 1

HCID 7410Acetophenone

Procedure

Following a procedure similar to that described in Example 3, 37.8 g. (0.1 mole) of 2-cyclohexylmethyl-1-[2-(3-bromophenyl)propyl]piperidine was reacted with 0.18 mole of n-butyl lithium in diethyl ether and the resulting lithio derivative reacted directly with 27 g. (0.23 mole) of acetophenone to give 11.8 g. of 2-cyclohexylmethyl-1-{2-[3-(α-hydroxy-α-methylbenzyl)phenyl]propyl}piperidine as a yellow oil.
