Reaction Conditions

Reaction Steps

To a toluene (5 ml) solution of the compound (0.287 g) obtained in Example 19-(4), Lawesson's reagent (0.275 g) was added and the mixture was stirred at 110° C. for an hour. After reversion to room temperature, the reaction mixture was concentrated to give a crude product, which was further purified by silica gel chromatography (AcOEt/hexane) to give the titled compound (0.100 g, colorless amorphous.)
