Reaction Steps

1 mL 85% H3PO4 was slowly drop added 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 6 were added to the poly phosphoric acid and heated for 5 hours at 100° C. After cooling down to RT, 10 mL icy cold water was added to reaction mixture. Product precipitated out as white solid. The product was collected and washed with water. 31 mg (82%) green colored product was collected after vacuum dry. MS only two peaks: M+1=384.4 with 304.4 (hydrolyzed back to 6).
