Benzenesulfonyl chloride → HCID 66973557, compound

Participants

Reaction Steps

To an 8 mL screw-cap vial were added pyridine (2 mL), N′-(5-fluoro-2-hydroxy-pyrimidin-4-yl)-N,N-dimethylformamidine (100 mg, 0.54 mmol), and benzenesulfonyl chloride (106 mg, 0.60 mmol), and the mixture was shaken at room temperature for 24 hours (h). The crude mixture was partitioned between ethyl acetate (EtOAc) and saturated aqueous sodium bicarbonate (satd aq NaHCO3), and the organic phase was dried over magnesium sulfate (MgSO4), filtered, and evaporated to yield 153 mg of crude material. Reverse phase chromatography furnished the title product as a white solid (33 mg, 19%): mp 203-204° C.; 1H NMR (300 MHz, CDCl3) δ 8.77 (s, 1H), 8.16-8.11 (m, 3H), 7.72-7.65 (m, 1H) 7.60-7.53 (m, 2H), 3.24 (s, 3H), 3.23 (s, 3H); ESIMS m/z 325 ([M+H]+).
