실험 절차
A solution of (3aR,6aS)-tert-butyl 5-bromo-4-oxohexahydrocyclopenta[c]pyrrole-2(1H)-carboxylate (300 mg, 0.986 mmol) from Step 1, 1H-imidazole (201 mg, 2.96 mmol), and acetone (0.5 mL) in a 4 mL vial was stirred for 1.5 h at 80° C. The reaction mixture was then concentrated. The crude product was purified chromatographically using a 12 g silica gel cartridge with a gradient of 0-10% CH3OH/CH2Cl2 over 20 min to give (3aR,6aS)-tert-butyl 5-(1H-imidazol-1-yl)-4-oxohexahydrocyclopenta[c]pyrrole-2(1H)-carboxylate: MS (ESI+) m/z 292 (M+H)+.
