Procedure

Tetra-n-butylammonium hydroxide (40% aq. w/w, about 150 g) was added dropwise to a solution of phosphoric acid (85% aq, w/w, 18 g, 0.155 mmol) in water (150 mL) until the pH reached 7. Water was then evaporated in vacuo to give a syrup which was co-evaporated with dry acetonitrile (2×400 mL) followed by dry toluene (2×400 mL). The resulting white solid (75 g) was dried in vacuo and stored over phosphorus pentoxide under vacuum until used.
