Potassium Carbonate → (9H-Carbazol-4-yloxy)acetonitrile

Participants

Reaction Steps

To a mixture of 9H-carbazol-4-ol (1.1 g, 6.0 mmol) in acetonitrile (100 mL) is added potassium carbonate (1.66 g, 12 mmol) and bromoacetonitrile (0.42 mL, 6.0 mmol). The mixture is stirred at room temperature for 20 h. The mixture is partitioned between water and CH2Cl2. The layers are separated and the organic layer dried over anhydrous sodium sulfate, filtered and concentrated. Column chromatography, silica gel (100 mL), using CH2Cl2 as eluent gave 1.13 g (85%) of the title compound; 1H NMR (DMSO-d6) δ5.4, 6.81, 7.18, 7.36, 7.46, 8.09; Anal. Calcd for C14H10N2O: C, 75.66; H, 4.53; N, 12.60. Found: C, 75.18; H, 4.56; N, 12.54.
