N-bromobutanimide → HCID 14696385, compound

Participants

Reaction Steps

To boiling CCl4 (250 mL) was added NBS (20.4 g, 0.114 mol) and AIBN (1.4 g, 0.009 mol). After 1 minute, a solution of 1-bromo-7-methylnaphthalene (24.1 g, 0.109 mol) in CCl4 (15 mL) was added all at once. Within 1 minute, the reaction became quite exothermic and the heating mantle was removed for several minutes. Heating was resumed for 30 minutes. The mixture was cooled, filtered, and the filtrate was concentrated to give an off-white solid (32.7 g). The product ws combined with similarly prepared material (32.6 g) and recrystallized from ethyl acetate/hexane to give the product (29.6 g, 45%).
