実験手順

N1-Isopropyl-5-(2-amino-4-pyridyl)oxy-1H-1-indolecarboxamide (90 mg, 0.29 mmol) was suspended in tetrahydrofuran (2 ml) at room temperature; triethylamine (0.121 mg, 0.868 mmol) and phenyl chloroformate (0.08 ml, 0.633 mmol) was added thereto while stirring; and the reaction mixture was stirred at room temperature for 2 hours. Water was added to the reaction mixture; this was subjected to extraction with ethyl acetate, washed with brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. N,N-Dimethylformamide (1 ml) and pyrrolidine (0.2 ml, 2.39 mmol) was added to the residue, and stirred at room temperature overnight. The reaction mixture was partitioned between ethyl acetate and water; the organic layer was dried over anhydrous sodium sulfate. This solution was concentrated under reduced pressure; and the residue was purified by silica gel column chromatography (Fuji Silysia NH, ethyl acetate-methanol). The resultant was washed with a solvent mixture (ether:hexane=1:1); and the solid was filtered off to yield the title compound as crystals (65 mg).
