Procedure
A mixture of 8-7 (5.5 g, 10.2 mmol) and POCl3 (50.0 g, 326.1 mmol) and DMF (0.3 g, 4.1 mmol) was heated to reflux at 130° C. for 3 hr. The reaction mixture was cooled and concentrated to remove POCl3. 40 mL Toluene was added and concentrated to obtain a solid. To the solid was added 50 mL H2O and 40 mL NaHCO3 (saturated) and 20 mL 1NNaOH to pH=9. The mixture was stirred to precipitate a solid which was collected via filtration as the desired product 8-8. It was washed by water and CH3CN and dried under vacuum.
