Procedure

1 g (3.47 mMol) of N-acetyl-N-[(S)-1-(2-piperidino-phenyl)-3-methyl-1-butyl]-amine (melting point: 128-133° C.; ee=99.4%] are refluxed in 10 ml of concentrated hydrochloric acid for 5.5 hours, then cooled and poured into a mixture of concentrated ammonia and ice. The mixture is extracted twice with ethyl acetate, the organic phase is washed with water, dried and filtered and then evaporated down in vacuo.
