実験手順

0.98 g (4 mmol) of 2-bromo-5-chloroindan-1-one and 0.42 g (6 mmol) of sodium thiomethoxide are suspended in 5 ml of ethanol, treated in an ultrasonic bath for 30 minutes and then stirred at room temperature for 90 minutes. The reaction mixture is concentrated under reduced pressure and chromatographed on silica gel using toluene/ethyl acetate 10/1. The eluates are concentrated under reduced pressure, giving 0.63 g of 5-chloro-2-methylsulfanylindan-1-one of melting point 90° C.
