Acetic Acid → N1-Methyl-5-(2-(((4-(morpholin-4-yl)piperidin-1-yl)carbonyl)amino)pyridin-4-yloxy)-1H-1-indolecarboxamide

Morpholine (228 mg, 1.64 mmol), sodium triacetoxyborohydride (372 mg, 1.76 mmol), and acetic acid (0.134 ml, 2.34 mmol) were added to a dichloromethane (3.5 ml) solution of N1-methyl-5-(2-(4-oxopiperidin-1-ylcarbonyl)amino-4-pyridyl)oxy-1H-1-indolecarboxamide (476 mg) 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 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 the title compound (110 mg) as crystals.
