Procedure

To a solution of [4-(2-fluoro-4-{[1-(4-fluorophenylcarbamoyl)cyclopropanecarbonyl]amino}phenoxy)pyridin-2-yl]-N-(phenoxycarbonyl)carbamic acid phenyl ester (80 mg) in N,N-dimethylformamide (1.0 ml) were added triethylamine (0.130 ml) and azetidine hydrochloride (60 mg) at room temperature, followed by stirring for 3 hr. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was washed with a saturated aqueous solution of sodium hydrogencarbonate and brine in this order, and dried over anhydrous sodium sulfate. The solvent was concentrated under reduced pressure. The resultant residue was purified by silica gel column chromatography (eluent; ethyl acetate). Fractions containing the target compound were concentrated under reduced pressure. To the resultant residue was added diethyl ether:heptane=1:2 to precipitate a solid. The solvent was concentrated under reduced pressure, and residue was dried under reduced pressure to provide the titled compound as white powder (41.7 mg, 69%).
