実験手順

To a solution of crude (2-{4-[(2,4-diamino-pteridin-6-ylmethyl)-methyl-amino]-benzoylamino}-propyl)-phosphonic acid diethyl ester post silica column chromatography (32.2 mg, 66.2 μmol) in dry DMF (0.50 mL) was added TMSBr (68.0 μL, 529.6 μmol) at ambient temperature. The solution was then heated at 70° C. for 1.0 hour, when LCMS analysis demonstrated the reaction to be complete. The reaction mixture was allowed to cool to room temperature, and water (60 μL) and methanol (60 μL) were added. The crude reaction mixture was purified by RP HPLC on C18 column using H2O/acetonitrile (2-95%) to provide 11.2 mg (38%) of the desired compound as a yellow solid. 1H NMR (300 MHz, DMSO-d6) δ 1.50 (m, 2H), 1.61 (m, 2H), 3.22 (s, 3H), 3.25-3.40 (m, 2H), 4.84 (s, 2H), 6.80 (d, 2H, J=9 Hz), 7.69 (d, 2H, J=9 Hz), 8.20 (br s, 1H), 8.69 (s, 1H). 31P (121.4 MHz, DMSO-d6) δ 26.3. MS (m/z) 447.3 [M−H]−.
