Procedure
To a solution of 4-(4-aminophenoxy)-2-{[4-(2-dimethylaminoethyl)piperazin-1-yl]carbonylamino}pyridine (137 mg) and (+)-10-camphorsulfonic acid (151 mg) in ethanol (3.5 ml) was added a solution of 2-phenylacetyl isothiocyanate in toluene (0.25 M, 2.73 ml) at room temperature, followed by stirring for 3 hours. 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 and brine in this order, 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, then ethyl acetate:methanol=98:2) to provide the titled compound (86.5 mg, 45%) as white powder.
