Chlorosuccinimide → (4R,9aR)-7-Chloro-4,6-dimethyl-3,4,9,9a-tetrahydro-1H-2,4a,5-triaza-fluorene-2-carboxylic acid tert-butyl ester

참여 물질

반응 단계

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.
