Reaction Steps

A mixture of compound 4,6-dichloro-2-phenyl-pyrimidine (27 g, 112 mmol), 4-trifluoromethoxy aniline (21 g, 119 mmol) and triethylamine (33 mL, 225 mmol) in n-butanol (300 mL) was refluxed for 20 hours under nitrogen atmosphere. The reaction mixture was then cooled to room temperature and concentrated under vacuum. The crude compound was passed through the silica gel by using 5-6% ethylacetate in petroleum ether to afford the compound (6-chloro-2-phenyl-pyrimidin-4-yl)-(4-trifluoromethoxy-phenyl)-amine (20 g, 46%) as off-white solid.
