Reaction Steps
1-(3-Bromophenyl)-3,3-dimethyl-pyrrolidine-2,5-dione (10.6 g, 37.7 mmol) was suspended in 200 ml of THF. Borane dimethyl sulfide complex (33 ml of a 10.1 M solution) was added and the reaction was stirred at room temperature for 3 hrs. The reaction was cooled in an ice bath. Methanol (100 ml) was added dropwise, followed by 300 ml of water. This mixture was transferred to a separatory funnel and DCM was added. The organic phase was isolated, washed with brine, filtered through Celite and concentrated. The product was chromatographed using a gradient of 0% to 5% ethyl acetate in hexanes, concentrated, triturated with methanol and filtered to give 8.0 g (84%) of 1-(3-bromophenyl)-3,3-dimethyl-pyrrolidine.
