Versuchsvorschrift

Azetidine hydrochloride (179 mg, 2.00 mmol) and sodium triacetoxyborohydride (434 mg, 2.05 mmol) were added to a dichloromethane (3.7 ml) solution of N1-methyl-5-(2-(4-oxopiperidin-1-ylcarbonyl)amino-4-pyridyl)oxy-1H-1-indolecarboxamide (555 mg, 1.36 mmol) synthesized in Example 40, and stirred overnight at room temperature. The reaction mixture was partitioned between ethyl acetate and water; and the organic layer was dried over anhydrous sodium sulfate. The solution was concentrated under reduced pressure; and the residue was purified by use of silica gel column chromatography (Fuji Silysia NH, ethyl acetate-methanol system). The resultant was washed with a solvent mixture of ether-hexane=1:1; and the solid was filtered off to yield crystals of the title compound (5 mg), and a mixture (410 mg) including the title compound.
