Reaction Steps

Pyridine (0.23 mL, 2.85 mmol) and trifluoromethanesulfonic anhydride (0.32 mL, 1.90 mmol) were added to a solution of N-ethylcarbamate-5-hydroxy-6-chloro-8-methyl-1,2,3,3a,8,8a-hexahydroindeno[1,2-c]pyrrole (0.28 g, 0.95 mmol) in CH2Cl2 (10 mL), and stirred for 1.5 hours at room temperature. The reaction was diluted with CH2Cl2 (10 mL), washed with H2O (10 mL), aqueous HCl (1.0 M, 10 mL), saturated aqueous NaHCO3 (10 mL), and brine (10 mL). The organic extract was dried over MgSO4 and concentrated to afford the subtitle compound, which was used without further purification. MS calculated for C16H17F3ClNO5S+H: 428, observed: 428.
