To anhydrous AlCl₃ (27.35 g, 205 mmol) and anisole (24.11 g, 223 mmol) in dry chloroform (300 mL) 2-bromobenzeneacetyl chloride [1] (43.4 g, 186 mmol) in dry chloroform (100 mL) was added over 30 min at 0 °C and stirred at ambient temperature for 15 h. 2 N HCl (100 mL) was added, and the mixture was extracted with CH₂Cl₂ (2 x 100 mL). The combined organic layer was washed with 2 N HCl (2 x 250 mL), water (2 x 250 mL), satd. NaHCO₃ (2 x 200 mL) and brine (200 mL), dried over Na₂SO₄, filtered and concentrated in vacuo. The residue was recrystallized from MeOH (50 mL). Yield: colorless crystals (51.3 g, 90%), mp. 87.5 - 88.5 °C.

TLC: petroleum ether : EtOAc = 80 : 20, R_f = 0.3.
