Reaction Steps

1 mL of 85% H3PO4 was slowly added (by drops) into 0.5 g of P2O5, the acid-anhydride mixture was then heated at 100° C. for 1 hour under nitrogen protection. Another 0.5 g of P2O5 and 30 mg of alcohol 6 were added to the poly phosphoric acid and heated for 5 hours at 100° C. After cooling down to room temperature, 10 mL cold water (0° C.) was added to reaction mixture. The product precipitated out as white solid, was collected and washed with water. 31 mg (82%) of green colored product was collected after vacuum drying. MS only two peaks: M+1=384.4 with 304.4 (hydrolyzed back to 6).
