WebThe resulting mixture was a dark brown oil that exothermed to 75° C. When the temperature had cooled to 50° C., Br2 was added dropwise over 15 min. The mixture, which had cooled further to 40° C., was heated to 80° C. for 5 min, then poured into a mixture of ice (600 g) and 12 N HCl (80 mL). All the ice melted, leaving a cool dark mixture ... WebThe reaction exothermed significantly and began to reflux the DCM solvent. Reaction was removed from the ice bath after ~1 hour, and then was allowed to stir overnight. Reaction was concentrated to approximately half the volume, then washed with 2 x 100 mL water. The water was then back-extracted with
