Procedure
To the resultant compound from Example 18A in methanol is added triethylamine (3.0 equivalent) and propane 1,3-dithiol (3.0 equivalents). After the reaction is judged complete by TLC analysis, the mixture is filtered and evaporated. Chromatography of the residue on silica gel provides the title product.
