Versuchsvorschrift
A mixture of 62.1 g (0.5 mol) of benzyl mercaptan and 78.1 g (0.5 mol) of (rac)-3-methyl-2-hexenoic acid ethyl ester of step (a) in 100 ml of piperidine was heated at reflux until complete reaction was observed (48 h), and cooled to room temperature. Then the excess of piperidine was distilled off at reduced pressure (0.04 mbar, 26-33° C.). The residue, 96.5 g (68%) of (rac)-3-benzylsulfanyl-3-methyl-hexanoic acid ethyl ester, was of good purity and was directly used in the next step.
