Reaction Steps

Aluminium chloride (4.80 g, 32.0 mmol, 1.0 eq.) and 1-phenyloctane (6.84 g, 32.0 mmol) were dissolved in dry dichloromethane (10 mL) and cooled to −10° C. A solution of bromoacetyl bromide (3.14 mL, 32.0 mmol, 1.0 eq.) in dichloromethane (12 mL) was added dropwise and the mixture was allowed to return to r.t. while stirring overnight. The mixture was slowly poured into ice water (100 mL) and the aqueous phase was extracted with dichloromethane (3×50 mL). The combined organic layers were dried over MgSO4 and concentrated under reduced pressure. The product was obtained as brown, highly viscous oil and was used in the next reaction without purification. Yield: 8.90 g (62%), purity: 69% (GC).
