Participants

Reaction Steps

To a solution of 5-cyanoindole (3.0 g, 21 mmol) in dry DMF (50 ml) was added N-chlorosuccinimide (2.94 g, 22 mmol) and the solution stirred at room temperature for 1 hour. The solution was left standing over the weekend. LC/MS showed a single product. Added ethyl acetate (150 ml) and diethyl ether (50 ml) and washed with water (3×300 ml). Dried over MgSO4 and evaporated off the solvent to yield 3.9 g of the title compound as a pale yellow solid. δH (400 MHz, d6-DMSO) 7.54 (1H, dd), 7.61 (1H, dd), 7.78 (1H, d), 8.01-8.02 (1H, m), 12.2 (1H, broad s). MS (from LCMS of reaction mixture) (ES):C9H5ClN2 requires 176; found 177 (MH+).
