NIS (6.75 g, 30.0 mmol) was added to a solution of 2-(2,4-difluorophenyl)-6,7-dihydro-5H-pyrrolo[1,2-a]imidazole (6.61 g, 30.0 mmol) in DMF (50 mL). The reaction mixture was stirred at ambient temperature for about 35 min and then partitioned between DCM and water. The organics were dried over MgSO4, filtered, concentrated under reduced pressure, and triturated with Et2O to give the title compound (4.49 g, 43%): LC/MS (Table 1, Method a) Rt=3.18 min; MS m/z: 347.2 (M+H)+.
