Participants

Reaction Steps

A suspension of tert-butyl[4-methyl-3-(trimethylsilyl)phenyl](trimethylsilyl)carbamate (3.00 g, 8.55 mmol), N-bromosuccinimide (NBS, 1.59 g, 8.97 mmol), 2,2′-azobis(2-methylpropionitrile) (AIBN, 42 mg, 0.26 mmol) in CCl4 (40 mL) was refluxed under N2 for 16 h. The reaction mixture was cooled down; hexanes (100 mL) were added and the solid was filtered off and washed with EtOAc. The combined filtrate was washed with aq. NaHCO3, dried over Na2SO4, filtered, concentrated on rotavap and further dried under vacuum. This material was not purified but used directly in the next step (˜80%).
