To a suspension of N′-(5-fluoro-2-hydroxypyrimidin-4-yl)-N,N-dimethylformamidine (0.10 g, 0.54 mmol) in pyridine (2 mL) was added benzene sulfonyl chloride (0.106 g, 0.60 mmol) and the mixture was agitated on an orbital shaker for 16 h at room temperature. The reaction mixture was partitioned between EtOAc and saturated aq NaHCO3, and the organic phase was dried over solid MgSO4, filtered, and concentrated under reduced pressure. Purification by reverse phase chromatography (H2O/MeCN gradient) afforded the title compound (0.089 g, 46% yield) as a white solid: mp 124-125° C.; 1H NMR (300 MHz, CDCl3) δ 8.54 (s, 1H), 8.12-8.07 (m, 3H), 7.73-7.66 (m, 1H), 7.62-7.56 (m, 2H), 3.21 (s, 6H); HPLC-MS (ESI) m/z 325 (M+H)+.
