Styrene → HCID 21224883, compound

Participants

Reaction Steps

N-bromosuccinimide (10.68 g, 0.06 mol) and cyanamide (4.2 g, 0.1 mol) were dissolved in 150 ml of dichloromethane and the mixture was stirred for 5 min. To this mixture was added a solution of styrene (5.2 g, 0.05 mol) in 20 ml of dichloromethane using a dropping funnel for one hour. The resulting reaction mixture was stirred at room temperature for 12 hours, washed with an equal volume of 5% sodium thiosulfate and brine which were freshly prepared, dried over anhydrous magnesium sulfate, concentrated, and then purified by silica gel column chromatography (eluent ethylacetate/toluene=1/20, v/v) to afford 8.98 g of 2-bromo-1-phenylethyl cyanamide.
