Procedure

To a solution of 24 (15 mg, 0.035 mmol) in 0.35 mL of CH2Cl2 (0.35 mL) was added diethyl(aminomethyl)phosphonate oxalate (27 mg, 0.105 mmol), EDC (20 mg, 0.105 mmol) and TEA (15 μL, 0.105 mmol). The solution was stirred at room temperature for 1 day when the same amount of the aminomethyl phosphonate, EDC and TEA were added. The reaction was stirred for another day when complete conversion of starting materials to the desired product was observed by LCMS. The product 26 was purified by reverse phase HPLC using 5-95% A. Buffer A contained CH3CN-1% HOAc and buffer B was H2O-1% HOAc. 1H NMR (300 MHz, CDCl3) δ 1.33-1.40 (m, 6H), 2.37-2.45 (m, 4H), 3.60-3.72 (m, 2H), 4.05 (s, 3H), 4.06-4.18 (m, 4H), 4.44 (d, 1H, J=15 Hz), 5.33 (d, 1H, J=14 Hz), 5.49 (s, 1H), 6.17 (br s, 1H), 6.98-7.08 (m, 2H), 7.33-7.43 (m, 2H), 7.55-7.63 (m, 1H), 8.50-8.57 (br d, 1H), 8.97 (br s, 1H); 31P (121.4 MHz, CDCl3) δ 22.7; 19F NMR (282.6 MHz, CDCl3) δ 62.6; EI MS (m/z) 590.4 [M−H]−, 614.2 [M+Na].
