The reaction mixture was then cooled to room temperature and concentrated under vacuum, the crude compound was passed through the silicagel by using 5-6% ethylacetate—petroleum ether to afford the compound [6-chloro-2-(4-fluoro-phenyl)-pyrimidin-4-yl]-(4-trifluoromethoxy-phenyl)-amine (0.75 g, 50%) as light brown solid.
