By following procedure A or B of Example 2 other indole-1-ethanethiol intermediates of formula III, for example those described in Examples 57 to 106 may be prepared by the appropriate choice of indole-1-ethanol intermediates of formula III. For example, by replacing 3-methylindole-1-ethanol with an equivalent amount of β-isopropyl-α,3,7-trimethylindole-1-ethanol, β-isopropyl-α,3,7-trimethyl-indole-1-ethanethiol is obtained. Likewise, by replacing 3-methylindole-1-ethanol with an equivalent amount of 3-isopropylindole-1-ethanol, 3-isopropylindole-1-ethanethiol is obtained.
