Procedure

To a solution of phenyl N-[4-(3-fluoro-4-{[1-(phenylcarbamoyl)cyclopropanecarbonyl]amino}phenoxy)pyridin-2-yl]-N-phenoxycarbonylcarbamate (50.0 mg) in N,N-dimethylformamide (1.0 ml) was added 3R)-(+)-3-dimethylaminopyrrolidine (44 mg), followed by stirring at room temperature for 3.5 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: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 solvent was removed, and the residue was dried under reduced pressure to provide the titled compound as white powder (33.2 mg, 79%).
