Versuchsvorschrift

4-(Pyrrolidin-1-ylmethyl)piperidine-1-carboxylic acid [6-(4-amino-2-fluorophenoxy)pyrimidin-4-yl]amide (100 mg) was dissolved in ethanol (1.0 ml) under a nitrogen atmosphere, and then (S)-(+)-10-camphorsulfonic acid (56 mg) was added thereto, followed by for stirring 5 min. A 0.25 M solution of phenylacetyl isothiocyanate in toluene (1.45 ml) was added thereto, followed by stirring for 1 hr. The reaction mixture was partitioned between ethyl acetate (30 ml) and a saturated aqueous solution of sodium hydrogencarbonate (20 ml). The organic layer was washed with a saturated aqueous solution of sodium hydrogencarbonate (20 ml), water (20 ml), brine (20 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; heptane:ethyl acetate=1:3). Fractions containing the target compound were concentrated to give a residue, to which diethyl ether (1.5 ml) and hexane (2.0 ml) in this order were then added to suspend. The solid was filtered off, and dried under aeration to provide the titled compound (37.6 mg, 26.4%) as pale yellow powder.
