Product 1

HCID 107212-Methylbenzonitrile

Procedure

Following a procedure similar to that described in Example 7, 18.9 g. (0.05 mole) of 2-cyclohexylmethyl-1-[2-(3-bromophenyl)propyl]piperidine was reacted with 0.095 mole of n-butyl lithium in diethyl ether and the resulting lithio derivative reacted directly with 12.4 g. (0.106 mole) of 2-methylbenzonitrile to give 4.85 g. of 2-cyclohexylmethyl-1-{2-[3-(2-methylbenzoyl)phenyl]propyl}piperidine as a yellow oil.
