A solution of 2-chloro-6-methylbenzonitrile (2.0 g) in conc. sulphuric acid (10 mL) was heated at 100° C. for 3-4 h. The reaction mass was quenched in ice-water and the solid obtained was filtered. The precipitate was suck dried to afford 1.5 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 2.28 (s, 3H), 7.21-7.27 (m, 3H), 7.65 (s, 1H), 7.91 (s, 1H).
