실험 절차

2-Amino-4-chloropyridine (500 mg, 0.446 mmol) was dissolved in N-methylpyrrolidone (5.0 ml); pyridine hydrochloride (750 mg) and 5-aminoindole-1-carboxylic acid phenylamide (408 mg, 1.62 mmol) was added thereto; the reaction mixture was stirred at 100° C. for 6.5 hours. After cooling to room temperature, the reaction mixture was partitioned between saturated aqueous solution of sodium hydrogencarbonate and ethyl acetate; the organic layer was washed with brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (Fuji Silysia NH, hexane-ethyl acetate-methanol system). The obtained pale yellow oil was solidified with diethyl ether; and the crystals were suspended in diethyl ether, filtered off, washed with diethyl ether, and dried to yield the title compound (188 mg, 0.464 mmol, 35.7%) as pale yellow crystals.
