Reaction Steps

The compound (1.26 g) obtained in Example 43-1 was dissolved in toluene (20 ml) and added with a Lawesson's reagent (1.29 g) and the whole was refluxed under heating for 2 hours. The reaction solution was cooled to room temperature and the precipitated solid was filtrated out. The resultant solid was subjected to recrystallization (methanol), thereby obtaining the subject compound (1.09 g) as a yellow solid.
