Procedure

NBS (70 mg, 0.4 mmol) was added to a solution of N-methylcarbamate-5-methoxy-8-methyl-1,2,3,3a,8,8a-hexahydroindeno[1,2-c]pyrrole (from Example 2, step A) (0.1 g, 0.36 mmol) in CH3CN (3.6 mL), and stirred overnight at room temperature. The reaction was diluted with H2O and EtOAc and filtered through an Extrelut column. The column was washed with EtOAc and the filtrate was concentrated to afford 120 mg (94%) of the subtitle compound. MS calculated for C16H20BrNO3+H: 342, observed: 342.
