Procedure

4,6-Dichloropyrimidine (250 mg, 3.3 mmol) and 4-trifluoromethoxy aniline (330.5 mg, 1.8 mmol) were dissolved in EtOH and DIEA (312.5 uL, 1.8 mmol) was added and the mixture was refluxed for 4 h. It was then cooled, concentrated and work-up with ethyl acetate. The organic layer was separated and dried (Na2SO4). Concentrated and purified by silica-gel column chromatography (Ethyl acetate/hexane). 400 mg (84% Yield). MS m/z 290.04 (M+1).
