Procedure

In 0.40 g of 4-formyl-2-methylbenzonitrile, 7 mL of concentrated sulfuric acid was added, and stirred at room temperature for 4.5 days. After the completion of the reaction, the reaction mixture was poured in 20 mL of ice water, extracted with ethyl acetate (15 mL×2). The combined organic phases were washed with water, and dehydrated with and dried over saturated sodium chloride aqueous solution and then anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The residue was washed with 5 mL of diisopropyl ether to obtain 0.26 g of the aimed product as white crystal.
