A mixture of ethyl {4-[(butylamino)methyl]-2-ethylphenoxy}acetate (0.23 g, 0.78 mmol), N,N-diisopropylethylamine (0.18 mL, 1.05 mmol) and 4-chloro-5-methyl-6-(4-methylphenyl)pyrimidine (0.114 g, 0.52 mmol) were heated at 100° C. in a sealed reactivial for 18 h. After this time the reactivial was allowed to cool to room temperature and the residue dissolved in CH2Cl2 (50 mL) and washed with water (10 mL) and brine (10 mL). The organic extract was separated by hydrophobic frit and evaporated. Purification by Biotage™ chromatography (Silica, 40 g) eluting 9:1 cyclohexane:EtOAc afforded the title compound as a pale yellow oil (46 mg).
