Mode opératoire

A solution of 3-aminopropylmethylphosphinic acid (137 mg, 1 mmol) and compound (17) (301 mg, 1 mmol) in acetonitrile (5 mL) and water (0.5 mL) was stirred at ambient temperature for 16 h. The solvent was removed under reduced pressure and the residue was purified by preparative HPLC to afford the title compound (111) as a white solid. 1H NMR (CDCl3, 400 MHz): δ 7.69 (br, 1H), 6.77 (q, 1H, J=5.2 Hz), 3.27 (t, 2H, J=6 Hz), 2.53 (m, 1H), 1.83-1.73 (m, 4H), 1.45 (m, 6H), 1.15 (d, 6H, J=7.2 Hz). MS (ESI) m/z 296.1 (M+H)+, 294.1 (M−H)−.
