Dimethylformamide → HCID 16118805, compound

Participants

Reaction Steps

To phenyl N-[4-(3-fluoro-4-{[1-(phenylcarbamoyl)cyclopropanecarbonyl]amino}phenoxy)pyridin-2-yl]-N-phenoxycarbonylcarbamate (50.0 mg) was added a solution of N-(1-ethylpiperidin-4-yl)-N-methylamine (66 mg) in N,N-dimethylformamide (1.0 ml), followed by stirring at room temperature for 9 hr. The reaction mixture was partitioned between ethyl acetate and 1N sodium hydroxide. The organic layer was washed with brine, and dried over anhydrous sodium sulfate. The solvent was removed, and the residue was purified by silica gel column chromatography (Fuji Silysia NH, ethyl acetate, then ethyl acetate:methanol=98:2). Fractions containing the target compound were concentrated. A solid was precipitated by addition of diethyl ether:hexane=1:2 to the residue. The solid was collected by filtration and dried under aeration to provide the titled compound as white powder (25.8 mg, 58%).
