実験手順

To a solution of the 2,4-dichloropyrimidine-5-carbonyl chloride (24 mmol) in THF (24 mL) is added H2O (0.64 mL) at room temperature. The reaction mixture is stirred at room temperature for 0.83 h and then diluted with H2O. The mixture is extracted with AcOEt. The organic extracts are washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo to give the crude titled compound; 1H NMR (CDCl3) δ 6.80 (brs, 1H), 9.18 (s, 1H).
