실험 절차

To a solution of 4-[(2,4-diamino-pteridin-6-ylmethyl)-methyl-amino]-benzoic acid hemihydrochloride dihydrate (61.2 mg, 161 μmol) in DMF (2.8 mL) were added diethyl cyanophosphonate (31.8 μL, 210 μmol) and DIEA (27.8 μL, 161 μmol). The solution was stirred at ambient temperature for 3 hours, when diethyl(aminopropyl)phosphonate (34.9 mg, 122.6 μmol) was added. The solution was stirred for 2 additional hours, whereupon complete consumption of the starting materials was observed. The reaction was worked up by removal of the solvent in vacuo and purifying the residue by silica gel chromatography using MeOH—CH2Cl2 (10-30%). The product (65.5 mg) collected from this chromatography step was sufficiently pure to be carried on to the next reaction. A small amount (32.8 mg) was re-purified by RP HPLC on C18 column using H2O/acetonitrile (2-95%) to provide 23.2 mg (75%) of the pure product. 1H NMR (300 MHz, DMSO-d6) δ 1.20 (t, 6H, J=7.2 Hz), 1.64-1.75 (m, 4H), 3.22 (s, 3H), 3.41 (m, 2H), 3.98 (appt septet, 4H, J=7.2 Hz), 4.85 (s, 2H), 6.79 (d, 2H, J=9 Hz), 7.68 (d, 2H, J=9 Hz), 8.17 (br s, 1H), 8.70 (s, 1H); 31P (121.4 MHz, DMSO-d6) δ 31.9; MS (m/z) 503.2 [M+H]+.
