실험 절차

To a solution of the product from example 12 (104 mg, 0.50 mmol) in DMF (2.0 ml) at 3° C. to 5° C. was added NaH (95%, 15 mg, 0.625 mmol). The resulting mixture was stirred for 15 min before adding acetic anhydride (0.083 ml, 0.875 mmol). The reaction was allowed to warm to RT and stirred for 3 h before pouring into with water (25 ml). The slurry was stirred for 12 h, and the product collected to give after chromatography (1:3 hexane-ethyl acetate) on silica gel 82 mg of 1-acetyl-7-chloro-β-carboline.
