An extra affirmation of structure four may very well be received by reacting 4c, like a representative, having an surplus of benzoyl chloride in pyridine to obtain the dibenzoate spinoff 9. It is evident that benzoylation is simply attainable for compound 4c and not for composition 5. When two was reacted with Every single of 3a-c by boiling in ethanolic potassium hydroxide, the S-alkylated derivatives 10a-c had been attained in weak yields. Compounds 10a-c may very well be cyclized by heating with acetic anhydride in pyridine to provide 4a-c, respectively (Plan 1).
