実験手順

To a solution of methyl (Z)-5-fluoro-2-methyl-1-(4-methylsulfinyl benzylidene)inden-3-yl acetate from Example 7 (3.7 g, 10 mmol) in methylene chloride (100 mL) there was added 85% m-chloroperoxy benzoic acid (2.54 g, 12.5 mmol) and the mixture was stirred at room temperature for 1 hour. There was added more methylene chloride (100 mL) then calcium hydroxide (5.5 g) and after 10 minutes, the suspension was filtered. The residue obtained by evaporation of the filtrate was stirred with ether (100 mL) at room temperature for 5 hours, then filtered to afford the title compound as a fluffy yellow solid, mp 162-164° C.
