실험 절차

A solution of 7-{(1S)-1-[(2-amino-9H-purin-6-yl)amino]ethyl}-6-(3-fluorophenyl)-3-methyl-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (27 mg, 62 μmol) in acetic acid (0.41 mL) and water (84 μL) at 0° C. was treated with a solution of sodium nitrite (13 mg, 0.19 mmol) in water (0.15 mL) dropwise and stirred at 0° C. for 30 minutes and at 20° C. for 16 hours. The reaction mixture was concentrated and purified by RP-HPLC (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 60 mL/min) to give the desired product (7 mg, 20%) as a white solid. LCMS for C20H17FN7O2S (M+H)+: m/z=437.8. 1H NMR (300 MHz, DMSO-d6): δ 7.79 (br s, 1H), 7.68-7.61 (m, 1H), 7.50-7.38 (m, 3H), 7.23-7.14 (m, 2H), 7.06 (br s, 1H), 5.02-4.92 (m, 1H), 2.64 (s, 3H), 1.26 (d, J=6.7 Hz, 3H).
