2-Methylsulfanyl-1H-pyrimidin-4-one (70 mg, 0.492 mmol, 1.41 eq) and 2-[4-(4-chloro-3-trifluoromethyl-phenoxy)-phenyl]-ethylamine (110 mg, 0.348 mmol, 1 eq) were heated in a sealed vial at 150° C. in 400 μl of dry pyridine for 16 hours. Solvent was then evaporated and the resulting crude was purified by chromatography on BIOTAGE SP1 purification device using 10 g normal phase silica SNAP column and DCM/30% MeOH in DCM solvent system (gradient 2-20% of 30% MeOH in DCM in 20 column volumes). Solvent from the gathered fractions of appropriate composition was evaporated and the resulting crude was triturated with diisopropyl ether and cyclohexane to afford 2-{2-[4-(4-chloro-3-trifluoromethyl-phenoxy)-phenyl]-ethylamino}-1H-pyrimidin-4-one (111 mg, yield=73.8%, purity=95%) as a white powder.
