실험 절차

Potassium tert-butoxide (3.4 g) was added to a room temperature solution of N-aminoindole (2.0 g) in 1-methyl-2-pyrrolidinone (40 ml). After stirring for one hour, 2-chloropyridine (1.6 ml) was added and the resulting solution was stirred for forty-eight hours. The reaction mixture was then quenched with water, diluted with ethyl acetate (250 ml) and washed with brine (3×250 ml). The organic layer was dried over anhydrous sodium sulfate and concentrated in vacuo to give an oil. Purification of the residue by flash chromatography (silica, 0-5% ethyl acetate/dichloromethane) gave the title compound as a solid (2.0 g), m.p. 109°-110° C.
