실험 절차

To a solution of 0.20 g (0.66 mmol) (R)-4,6-dimethyl-3,4-dihydro-1H-2,4a,5-triaza-fluorene-2-carboxylic acid tert-butyl ester in 2 mL tetrahydrofuran was added 92.1 μg (0.69 mmol) N-chlorosuccinimide. The reaction was stirred at 50 deg C. for 18 h, then the solvent was evaporated and the residue was purified by column chromatography on silica gel (0.032–0.063 mm) with ethyl acetate:dichloromethane (1:19) as eluant.
