The alkylation of the alpha-N-piperidinylethyl derivative of the 2-chlorophenylacetonitrile (I) with N-benzyl-N-isopropylaminoethyl chloride (II) (4) and sodium amide in refluxing toluene gives (rac)-alpha-(2-chlorophenyl)-alpha-[2-[(1-methylethyl)(phenylmethyl) amino]ethyl]-1-piperidinebutanenitrile (III). Hydration of the nitrile (III) with sulfuric acid provided (rac)-alpha-[1-[(1-methylethyl)(phenylmethyl)amino]ethyl]-1-piperidinebutanamide (IV), and subsequent catalytic hydrogenolysis of the N-benzyl group yielded (rac)-alpha-(2-chlorophenyl)-alpha-[(1-methylethyl)amino]ethyl] piperidinebutanamide (V). Final acylation of the secondary amine (V) with acetyl chloride in chloroform in the presence of triethylamine was carried out at 0 C to provide bidisomide (SC-40230).
