Procedure

To a solution of phenyl N-[4-(3-fluoro-4-{[1-(4-fluorophenylcarbamoyl)cyclopropanecarbonyl]amino}phenoxy)pyridin-2-yl]-N-phenoxycarbonylcarbamate (60.8 mg) in N,N-dimethylformamide (1.0 ml) was added (3R)-(+)-3-dimethylaminopyrrolidine (41.7 mg), followed by stirring at room temperature for 7 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=20:1). Fractions containing the target compound were concentrated. To the residue was added diethyl ether:hexane=1:2, and the precipitated solid was collected by filtration. This was dried under aeration to provide the titled compound as white powder (18.3 mg). This was purified again by silica gel column chromatography (Fuji Silysia NH, hexane:ethyl acetate=1:2, ethyl acetate, then ethyl acetate:methanol=20:1). Fractions containing the target compound were concentrated. To the residue was added diethyl ether:hexane=1:2, and the precipitated solid was collected by filtration. This was dried under aeration to provide the titled compound as white powder (12.3 mg, 23.8%).
