Procedure

NCS (63 mg, 0.47 mmol) and acetic acid (1 mL) were added to a solution of N-ethylcarbamate-5-methoxy-8-methyl-1,2,3,3a,8,8a-hexahydroindeno[1,2-c]pyrrole (from Example 2, Step A) (43 mg, 0.16 mmol) in DCE (1 mL), and the reaction solution was stirred for 3 hours at 70° C. The reaction was quenched with H2O and the solution filtered through an Extrelut column. The column was washed with CH2Cl2, and the filtrate was concentrated. The subtitle compound was obtained without further purification. MS calculated for C16H19Cl2NO3+H: 344, observed: 344.
