实验步骤: To a cold (0° C.) solution of 4-methylpyrimidine (4.56 mL 50.1 mmol) and ethyl 3-chlorobenzoate (7.90 mL 50.1 mmol) in tetrahydrofuran (50 mL) was added lithium bis(trimethylsilyl)amide (100 mL, 1.0M in tetrahydrofuran, 100 mmol) dropwise over 30 minutes. The resultant mixture was warmed to room temperature and stirred 16 hours. The reaction mixture was concentrated in vacuo. The resultant oil was diluted with methanol. Upon standing, a solid precipitated, which was collected on a filter to provide 1-(3-chlorophenyl)-2-(4-pyrimidinyl)ethenol (11.2 g, 93%) as a yellow solid. Rf 0.31 (3:1 hexanes:ethyl acetate); 1H NMR (d6-DMSO) δ 8.37 (s, 1H), 7.98 (m, 1H), 7.81–7.76 (m, 2H), 7.38–7.32 (m, 2H), 6.71 (br, 1H), 5.65 (s, 1H); MS m/z 233 (M+1).
