実験手順
Reaction of 4-bromoaniline with α-cyclohexylacetyl chloride in the presence of pyridine and reaction of the resulting N-(4-bromophenyl)-α-cyclohexylacetamide with sodium hydride in DMF followed by reaction of the resulting sodium salt with chloramine all according to the procedure described in Example 65 affords N'-cyclohexylacetyl-4-bromophenylhydrazine. Reaction of the latter with levulinic aldehyde diethylacetal in refluxing ethanol using the procedure described above in Example 1, and reduction of the resulting 1-cyclohexylacetyl-5-bromo-2-methylindole-3-acetaldehyde in the presence of a molar excess of 2-cyclohexylmethylpiperidine under 600 pounds p.s.i.g. of hydrogen at a temperature of 100° C. over a Randy nickel catalyst affords 1-cyclohexylacetyl-3-[2-(2-cyclohexylmethylpiperidino)ethyl]-5-bromo-2-methylindole.
