Versuchsvorschrift
Stirred the solution of 4-(bromomethyl)benzonitrile (1.5 g) in cocn.H2SO4 at 100° C. for 3-4 h. After completion of the reaction, the reaction mass was quenched in ice and filtered to afford 0.900 of desired product. 1H NMR (400 MHz, DMSO d6): δ 4.71 (s, 2H), 7.26 (br s, 1H), 7.49 (d, J=7.8 Hz, 2H), 7.82 (d, J=7.8 Hz, 2H), 7.89 (br s, 1H); MS (m/z): 214.36 (M+H)+.
