Procedure: To a solution of (2-methyl-propenyl)-benzene (2.6 g, 19.67 mmol) in propionitrile (20 g, 363 mmol) H2SO4 (39.33 mmol) was added at 10° C. The mixture was stirred at room temperature for 16 h. Then the mixture was poured into water and adjusted to an alkaline pH with NaOH. The aqueous layer was extracted three times with ethyl acetate, the organic layers combined, washed with water and brine, dried over MgSO4, filtered, and the solvent evaporated under reduced pressure to give the product as a yellow oil (1.6 g, 40%). The aqueous layer was extracted three times with ethyl acetate washed with water and brine dried over MgSO4 filtered the solvent evaporated under reduced pressure
