5-(6-methyl-pyridin-3-ylmethyl)-2-methylsulfanyl-1H-pyrimidin-4-one (50 mg, 0.202 mmol, 1 eq) and 2-[4-(4-chloro-3-trifluoromethyl-phenoxy)-phenyl]-ethylamine (100 mg, 0.317 mmol, 1.57 eq) were heated in a sealed vial at 130° C. in 300 μl of absolute ethanol for 20 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/20% MEOH in DCM solvent system (gradient 5-40% of 20% MeOH in DCM in 25 column volumes). Solvent from the gathered fractions of appropriate composition was evaporated and the resulting crude was purified once more under the same conditions. Solvent from the gathered fractions of appropriate composition was evaporated the resulting oil was triturated with cyclohexane and diethyl ether to afford 2-{2-[4-(4-chloro-3-trifluoromethyl-phenoxy)-phenyl]-ethylamino}-5-(6-methyl-pyridin-3-ylmethyl)-1H-pyrimidin-4-one (51 mg, yield=46.54%, purity=95%). MS: [M+H]=515.34. 1H NMR (300 MHz; CDCl3) δ/ppm 2.48 (s, 3H), 2.87 (t, J=7.23 Hz, 2H), 3.57 (s, 2H), 3.52-3.62 (m, 4H), 5.55 (br.s., 1H), 6.93 (d, J=8.23 Hz, 2H), 6.98-7.06 (m, 2H), 7.21 (d, J=8.23 Hz, 1H), 7.28 (d, J=2.84 Hz, 1H), 7.36-7.43 (m, 2H), 7.60 (br.s., 1H), 8.39 (s, 1H).
