Reaction Steps
[5-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-pentyl]-phosphonic acid diethyl ester (0.300 g, 0.849 mmol) was dissolved in THF [2 mL], IPA [4 mL]. Hydrazine (0.081 g, 2.540 mmol) was added to this solution and stirred at room temperature for 18 hours. The white precipitate was filtered and washed with dichloromethane. Removal of the solvent in vacuo yielded the title compound (0.136 g, 72%) 1H-NMR (CDCl3): δ 4.07 (m, 4H), 2.68 (t, 2H, J=6.74 Hz), 1.72 (m, 2H), 1.60 (m, 2H), 1.43 (m, 4H), 1.31 (m, 6H).
