Reaction Steps

To a solution of methyl 2-methoxy-4-methylbenzoate (10.00 g, 55 mmol) in CCl4 (150 mL) were added NBS (11.8 g, 66 mmol) and AIBN (0.100 g). The reaction mixture was refluxed for 18 h. The reaction mass was diluted with diethyl ether and washed with 25% NaOH solution. The organic layer was dried over anhydrous sodium sulphate and concentrated to afford 10.00 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 3.77 (m, 6H), 4.68 (s, 2H), 7.06 (d, J=7.8 Hz, 1H), 7.23 (s, 1H), 7.61 (d, J=7.8 Hz, 1H); MS (m/z): 259.13 (M)+.
