To a solution of 2-chloro-5-iodo-N-propylpyrimidin-4-amine (F1, 596 mg) and 3-fluoroaniline (1.11 g) in N-methylpyrrolidone (10 mL), (1S)-(+)-10-camphorsulfonic acid (2.32 g) was added at room temperature, and the mixture was stirred at 40 to 50° C. for 6 hours. The reaction mixture was cooled to room temperature, and then saturated aqueous sodium hydrogencarbonate was added to the reaction mixture. The solid matter was taken by filtration, washed with water, and then dried under reduced pressure to obtain N2-(3-fluorophenyl)-5-iodo-N4-propylpyrimidine-2,4-diamine (F2, 685 mg) as white solid.
