Bromotrimethylsilane → 1,5-Dibromo-2,3-dihydro-1H-indene

Participants

Reaction Steps

To a nitrogen-purged flask was added 100 mg (0.469 mmol) of 5-bromoindan-1-ol from Step A and 3 mL of anhydrous chloroform, followed by 0.096 mL (0.704 mmol) of bromotrimethylsilane. The reaction mixture was stirred at ambient temperature overnight and concentrated. The residue was partitioned between ethyl acetate and water. The organic phase was washed with saturated aqueous sodium chloride solution, dried over sodium sulfate, and concentrated to give a brown oil which was used without further purification. Mass spectrum (MS): m/z 195, 197 (M+1-HBr), 116 (M+1-2HBr).
