Participants

Reaction Steps

After dissolving (3-fluoro-4-{2-[3-methyl-3-(1-methylpiperidin-4-yl)ureido]pyridin-4-yloxy}phenyl)carbamic acid benzyl ester (38.7 mg) in tetrahydrofuran (1.5 ml) and methanol (1.5 ml), 10% palladium-carbon (16 mg) was added under a nitrogen atmosphere. The atmosphere in the reaction vessel was replaced with hydrogen, and the mixture was stirred for 5 hours at room temperature. The catalyst was filtered and then washed with methanol. The filtrate was concentrated under reduced pressure to provide a crude product of the title compound as a pale yellow oil (28.5 mg).
