Application
Eaton’s Reagent: A Less Viscous Alternative to PPA
Experimental procedure5): 1 (1.8g, 6.6 mmol) is added to a flask and phosphorus pentoxide-methanesulfonic acid (7 mL) is then added to the flask. Reaction mixture is aged at 50 °C, and progress of reaction is followed by HPLC. The reaction mixture is cooled to 5 °C and slowly transferred to an excess saturated sodium carbonate solution (10 eq.) that is cooled to 10 °C. Solid is filtered and washed with water (20 mL) and is dried in a vac. oven at 50 °C for 12 h. 2 is isolated in 97% yield (1.5g, 6.4 mmol).
