実験手順

4-(Pyrrolidin-1-ylmethyl)piperidine-1-carboxylic acid [4-(4-amino-2-fluorophenoxy)pyridin-2-yl]amide (50 mg) was dissolved in N,N-dimethylformamide (1.5 ml) under a nitrogen atmosphere, and then 0.25 M 2-phenylacetyl isocyanate in hexane (1.45 ml) was added, followed by stirring for 64.5 hrs. The reaction mixture was partitioned between ethyl acetate (100 ml) and a saturated aqueous solution of sodium hydrogencarbonate (50 ml). The organic layer was washed with a saturated aqueous solution of sodium hydrogencarbonate (50 ml), water (50 ml) and brine (50 ml) in this order, and dried over anhydrous sodium sulfate. The solvent was evaporated to give a residue, which was then purified by silica gel column chromatography (Fuji Silysia NH, eluent; ethyl acetate). Fractions containing the target compound were concentrated to give a residue, which was then suspended in diethyl ether (3 ml) and hexane (3 ml). The solid was filtered off, and dried under aeration to provide the titled compound (49.1 mg) as white powder.
