Procedure
5 mmol of 3-(1-triphenylmethyl-1H-imidazol-4-yl)propanal (prepared according to standard methods (Swern oxidation) with 3-(1-triphenylmethyl-1H-imidazol-4-yl)propanol and oxalyl chloride in DMSO at −45° C.) and 5 mmol of 3-phenylpropyltriphenylphosphonium bromide (prepared from triphenylphosphine and 3-phenylpropyl bromide in toluene under reflux for 12 h) are treated as described in Example 51. The 1-(1H-imidazol-4-yl)-6-phenyl-3-hexene is hydrogenated as described in Example 52. The title compound is crystallized in the form of hydrogen oxalate in ethanol and diethyl ether.
