Versuchsvorschrift
4-(1-Methyl-4-oxido-1,4-azaphosphinan-4-yl)phenol (0.50 g, 2.22 mmol) was made 0.5 M in DMF and N-Phenyl-bis(trifluorometanesulfonamide (1.19 g, 3.33 mmol) was added, followed by TEA (0.62 mL, 4.44 mmol). The mixture was stirred at ambient temperature for 16 h then the precipitate was filtered off and the filtrate was concentrated in vacuo. The residue was purified by HPLC (20-95% MeCN in water w/0.025% TFA). Pure fractions were identified, combined and concentrated in vacuo. The residue was taken up in EtOAc and washed with saturated aqueous sodium bicarbonate (1×) then dried (MgSO4) and concentrated in vacuo to afford the requisite product as a freebase.
