Subsequently, the flask wassealed with a glass stopper and submerged in an oil bath at 130 C. Thereaction mixture was stirred vigorously for 20 h and the flask was allowed to cool down to ambient temperature. Then, distilled water (150 mL) was added to the reaction mixture, followed by 10% (v/v)aqueous HCl solution, until pH reached the value of 1-2. The product and unreacted 2-iodobenzonitrile precipitated, and was filtered, and washed with water several times. Then, 0.1 N NaOH (500 mL) was added to the precipitate to get a suspension. This suspension wasfilteredto remove the unreacted 2-iodobenzonitrile and the filtrate was collected. Subsequently, 10% (v/v) aqueous HCl solution was added to the filtrate until pH reached the value of 1-2 and the product precipitated. The precipitate was filtered, and washed with water several times, and thenwith diethyl ether. The obtained product was dried under vacuum at 40 C for 24 h and theyield was determined (8.9 g, 75%). 1H NMR (400 MHz, (CD3)2SO): delta 8.10 (d, J = 7.9 Hz, 1H), 7.60 (d, J = 4.1 Hz, 2H), 7.42 – 7.30 (m, 1H).13C{1H} NMR (101 MHz, (CD3)2SO): delta 156.97, 140.26, 132.87, 131.73, 131.01, 128.94, 98.11.
