실험 절차

Following a procedure similar to that described in Example 3, 18.9 g. (0.05 mole) of 2-cyclohexylmethyl-1-[2-(3-bromophenyl)propyl]piperidine was reacted with 0.1 mole of n-butyl lithium in diethyl ether and the resulting lithio derivative reacted directly with 12.3 g. (0.103 mole) of 4-methylbenzaldehyde to give 16.9 g. of 2-cyclohexylmethyl-1-{2-[3-(α-hydroxy-4-methylbenzyl)phenyl]propyl}piperidine as a yellow oil.
