Water was added to the reaction mixture in small portions under ice-cooling, followed by stirring for 10 minutes. Magnesium sulfate was added thereto and then stirred for 10 minutes. The reaction mixture was filtered through Celite and the filtrate was concentrated under reduced pressure to obtain 13 g of the desired compound.
