実験手順

NBS (34 mg, 0.2 mmol) was added to a solution of N-Ethylcarbamate-5-methyl-8-methyl-1,2,3,3a,8,8a-hexahydroindeno[1,2-c]pyrrole (from Example 21, Step A) (50 mg, 0.2 mmol) in acetonitrile (1 mL), and stirred overnight at room temperature. The reaction was diluted with CH2Cl2 (3 mL) and H2O (3 mL) and filtered through an Extrelut column. The column was washed with CH2Cl2 and the filtrate was concentrated. The crude product was purified by column chromatography (SiO2) using a 0-50% EtOAc-hexanes gradient to afford the subtitle compound. MS calculated for C16H20BrNO2+H: 338, observed: 338.
