Procedure

Carbazole (1.10 g, 6.59 mmol) was dissolved in CH3CN (40 mL). Then sodium hydrate (0.33 g, 8.25 mmol) was added, and the mixture was stirred at room temperature for 15-20 min. Then, a solution of aziridine 56 (1.5 g, 7.89 mmol) in CH3CN (30 mL) was added in one portion. The resulting mixture was stirred for 1 h (TLC monitoring, eluent: hexane-ethyl acetate, 1:1), poured into water, acidified with HCl to pH 1, and stirred again at room temperature. Gradually, an orange product precipitated from the turbid solution. The precipitate was filtered, and washed with MeOH and ether. Yield of 51: 2.15 g (83%) as orange crystals.
