Versuchsvorschrift

HBr gas was bubbled through a solution of (4-isobutyl-phenyl)-methanol (5 g, 28 mmol) in Et2O (50 mL) for 10-15 minutes. The reaction was stirred for 1 h and was poured onto ice (100 g). Et2O was added and the organic solution was washed with brine (2×). The organic solution was dried (MgSO4), filtered, and concentrated to provide the title compound (6 g). 1H NMR (400 MHz, CDCl3) δ 7.28 (d, 2H), 7.10 (d, 2H), 4.49 (s, 2H), 2.45 (d, 2H), 1.84 (m, 1H), 0.89 (d, 6H).
