Reaction Steps

A mixture of 2-chloro-6-[4-(trifluoromethyl)phenyl]pyrazine (0.172 g, 0.56 mmol), ethyl {4-[(butylamino)methyl]-2-ethylphenoxy}acetate (0.25 g, 0.85 mmol) and N,N-diisopropylethylamine (0.099 mL, 0.56 mmol) were heated together in a reactivial at 100° C. for 18 h. The vial was then allowed to cool to room temperature and the residue dissolved in CH2Cl2 (50 mL) and the organic solution washed with water (15 mL) and brine (10 mL). The solution was then passed through a hydrophobic frit and evaporated. Purification by Biotage™ chromatography (Silica, 40 g) eluting 9:1cyclohexane:EtOAc, afforded the title compound as a pale yellow oil (50 mg).
