Reaction Steps

To 45 parts of cooled ethyl α-cyano-α-methyl-1-(phenylmethyl)-4-piperidineacetate were added 250 parts of a sodium hydroxide solution 2N. After stirring overnight at room temperature, the reaction mixture was cooled, neutralized with hydrochloric acid and then evaporated. The residue was taken up in 45 parts of N,N-dimethylacetamide and the whole was heated for 5 hours at 150° C. and then evaporated again, yielding 16 parts (30.3%) of α-methyl-1-(phenylmethyl)-4-piperidineacetonitrile monohydrochloride (int. 31).
