Procedure

4-Hydroxybenzonitrile (30.0 g, 252 mmol), allyl bromide (39.6 g, 327 mmol), and Cs2CO3 (98.5 g, 302 mmol) were dissolved in DMF (900 mL), and water (1 mL) was added. After stirring for 12 h at rt, the reaction mixture was concentrated under reduced pressure, water was added, and the mixture was extracted with EtOAc (2×). The combined organic layers were washed with water and brine. The organic layer was dried over Na2SO4, filtered, and concentrated under reduced pressure yielding 40 g (100%) of the title compound as a white crystalline solid. 1H NMR (400 MHz, CDCl3): δ 4.60 (d, 2H), 5.34 (d, 1H), 5.43 (d, 1H), 6.03 (m, 1H), 6.96 (d, 2H), 7.58 (d, 2H).
