Procedure

To a 500 mL round-bottom flask was added 4-phenyl-[1,4]azaphosphinane 4-oxide hydrochloride salt (5.91 g, 25.6 mmole), MP-carbonate resin (20 g, 2.9 mmole/g), and water (200 mL). The flask was sealed with a plastic stopper and placed on an orbital shaker for 12 hours. The resin was then removed by filtration with though a glass frit, and washed with water (40 mL) to provide 4-phenyl-[1,4]azaphosphinane 4-oxide free-base as an aqueous solution.
