Participants

Reaction Steps

To a solution of phenylphosphinic acid (5.00 g, 35.2 mmol), anhydrous methanol (7.0 mL, 170 mmol) and 4-dimethylaminopyridine (425 mg, 3.48 mmol) in 50 mL of THF (distilled from ketyl) was added EDAC (8.05 g, 42 mmol) at room temperature. The reaction was stirred for 24 hours then partitioned between HCl solution (75 mL of 1M aq) and ethyl acetate (75 mL). The organic layer was separated, washed with HCl solution (75 mL of 1M aq), sodium bicarbonate solution (75 mL of 5% aq) then dried (sodium sulfate) and concentrated in vacuo to afford the crude title compound as a colorless liquid (1.24 g, 7.95 mmol, 23%).
