실험 절차

To a solution of 2-(6-fluoro-1H-benzo[d]imidazol-1-yl)-8-oxo-9-(tetrahydro-2H-pyran-4-yl)-8,9-dihydro-7H-purine-6-carboxylic acid (25 mg, 0.063 mmol) in THF (2 mL) at 0° C. was added piperidine (8 mg, 0.09 mmol) and triethyl amine (0.052 mL, 0.37 mmol), followed by a solution of triphenylphosphine (0.056 mL, 0.18 mmol) in ethyl acetate. The reaction mixture was allowed to reach room temperature and stirred for 24 h. The solvent was evaporated and a saturated solution of sodium bicarbonate was added to the residue. The solid formed was filtered and dried to give the desired compound as a white solid. Yield: 10 mg, 34%. 1H NMR (400 MHz, DMSO-d6) δ, ppm: 11.89 (s, 1H), 8.20 (d, J=8.5 Hz, 1H), 7.82 (dd, J=4.8, 4.8 Hz, 1H), 7.24 (t, J=6.94 Hz, 1H), 4.58 (m, 1H), 4.03 (t, J=2.2 Hz, 2H), 3.68 (m, 2H), 3.68-3.48 (m, 4H), 2.64-2.55 (m, 2H), 1.79 (d, J=11.6 Hz, 2H), 1.66 (m, 4H), 1.55 (m, 2H); LCMS (EI) m/z 466 (MH)+.
