Procedure

To a solution of 3-aminopropylphosphonous acid (10 mmol) and sodium bicarbonate (20 mmol) in water (40 mL) is added a solution of compound (17) (10 mmol) in acetonitrile (20 mL) over 1 min. The reaction is stirred at ambient temperature for 16 h. The reaction mixture is diluted with diethyl ether (100 mL) and washed with 0.1 M aqueous potassium bisulfate (3×100 mL). The organic phase is separated, dried over anhydrous magnesium sulfate, filtered, and concentrated in vacuo to afford the title compound (31) as a white solid.
