Reaction Conditions

Reaction Steps

0.6 g (2.3 mmol) of 2-bromo-5-chloro-3-hydroxyindan-1-one and 0.473 g (3.45 mmol) of thiobenzamide were dissolved in 5 ml of isopropanol. 0.478 ml (3.45 mmol) of triethylamine was added, and the mixture was then stirred at room temperature for 12 h and subsequently at 50° C. for 8 h. The cooled reaction mixture was concentrated under reduced pressure and the residue was purified by chromatography on silica gel by initially using n-heptane/ethyl acetate 3/1 and then toluene/acetone 5/1. This gave 6-chloro-2-phenyl-8,8a-dihydroindeno[1,2-d]thiazole-3a,8-diol having a melting point of 151-153° C. (with decomposition).
