A mixture of 4-chloro-5-methyl-6-[4-(trifluoromethyl)phenyl]pyrimidine (0.229 g, 0.84 mmol), N,N-diisopropylethylamine (0.293 mL, 1.68 mmol) and ethyl {4-[(butylamino)methyl]-2-methylphenoxy}acetate (0.35 g, 1.26 mmol) was heated at 100° C. in a sealed reactivial for 18 h. The reaction mixture was then allowed to come to room temperature, and the residue dissolved in CH2Cl2 (50 mL), the organic extract was washed water (20 mL) and passed through a hydrophobic frit then concentrated in vacuo. Purification by Biotage™ chromatography (Silica, 90 g) eluting with 1:19–1:9 EtOAc:cyclohexane afforded the title compound as a colourless oil (0.19 g).
