To the cold solution was added a solution of 0.2 g (1.33 mmol) of 2,4-dichloro-1,3,5-triazine in 2.4 mL of dry acetonitrile over 1 min. The reaction mixture was stirred for ca. 16 hrs and 1 gram of silica gel was added. The mixture was concentrated in vacuo to dryness and applied to the top of column of silica gel and eluted with a 15-50% ethyl acetate/dichloromethane gradient. The proper fractions were combined and concentrated in vacuo to give 0.28 g (70%) of 4-chloro-N-{3-[(methylsulfonyl)methyl]phenyl}-1,3,5-triazin-2-amine as a white solid.
