Participants

Reaction Steps

To a suspension of tert-butyl 3-oxopyrrolidine-1-carboxylate (2.40 g, 0.0130 mol), 4-bromo-2-methyl-2-butene (3.00 mL, 0.0260 mol) in 15.0 mL, sat'd. ammonium chloride and tetrahydrofuran (3.00 mL, 0.0370 mol) was added zinc (1.70 g, 0.0260 mol) at rt. Soon after stirring was started, gas and heat were released. After 30 to 45 min., the resulting light grey mixture was filtered through celite. The filtration was extracted with EtOAc. The organic layers were combined, washed with brine, dried (NaSO4) and concentrated in-vacuo. The residue was purified on silica gel, eluting with 0 to 40% EtOAc in hexane, to give the desired product. LCMS (M+Na) 278.2.
