Procedure

BBr3 (0.3 mL, 0.30 mmol, 1 M in CH2Cl2) was added to a solution of N-Ethylcarbamate-5-methoxy-6-chloro-8-methyl-1,2,3,3a,8,8a-hexahydroindeno[1,2-c]pyrrole (from Example 3, Step A) (46 mg, 0.15 mmol) at 0° C., and stirred overnight at room temperature. The reaction solution was quenched with H2O and filtered through an Extrelut column. The column was washed with CH2Cl2, and the filtrate was concentrated. The crude product was obtained without further purification. MS calculated for C15H18ClNO3+H: 296, observed: 296.
