Reaction Steps

To the compound (3.67 g, 9.28 mmol) obtained in step A was added phosphorus oxychloride (30 g), and the mixture was stirred at 110° C. for 2.5 hr. After cooling to room temperature, the reaction mixture was poured into ice water, and the solution was extracted with ethyl acetate. The organic layer was washed with water, saturated aqueous sodium hydrogen carbonate and saturated brine, and dried over anhydrous magnesium sulfate. The insoluble material was filtered off, and the solution was concentrated under reduced pressure to give the title compound (2.00 g, yield 59%) as a colorless solid.
