Procedure

2-Phenylacetyl chloride (0.068 ml) was dissolved in acetonitrile (5 ml) under a nitrogen atmosphere, and then potassium thiocyanate (100 mg) was added thereto at 60° C., followed by stirring at the same temperature for 1.5 hrs. The reaction mixture was cooled down to room temperature, and then a solution of piperidine-1-carboxylic acid [6-(4-amino-2-fluorophenoxy)pyrimidin-4-yl]amide (114 mg) in acetonitrile (3 ml) was added thereto, followed by stirring for 30 min. The reaction mixture was partitioned between ethyl acetate and a saturated aqueous solution of sodium hydrogencarbonate. The organic layer was washed with a saturated aqueous solution of sodium hydrogencarbonate, water and brine in this order, and dried over anhydrous sodium sulfate. The solvent was evaporated under a reduced pressure to give a residue, which was then purified by silica gel column chromatography (eluent; hexane:ethyl acetate=1:1). Fractions containing the target compound were concentrated to give a residue, which was suspended in diethyl ether (5 ml)-hexane (5 ml). The solid was filtered off and dried under aeration to provide the titled compound (88.8 mg, 50.8%) as a pale yellow solid.
