Procedure

After adding a solution of 2-(4-fluorophenyl)acetyl isothiocyanate in toluene (0.25 M, 3.0 ml) to a solution of 4-(4-aminophenoxy)-2-{[4-(1-methylpiperazin-4-yl)piperidin-1-yl]carbonylamino}pyridine (149 mg) and (+)-10-camphorsulfonic acid (152 mg) in ethanol (4.0 ml) at room temperature, the mixture was stirred for 3 hours. The reaction mixture was partitioned between ethyl acetate and saturated aqueous sodium hydrogencarbonate. The organic layer was washed with saturated aqueous sodium hydrogencarbonate and brine and dried over anhydrous sodium sulfate. The solvent was then distilled off, and the residue was purified by silica gel column chromatography (Fuji Silysia NH, eluent; ethyl acetate:methanol=98:2 to 97:3) to provide the title compound (88.2 mg, 40%) as white powder.
