2-methylsulfanyl-5-(6-oxo-1,6-dihydro-pyridin-3-ylmethyl)-1H-pyrimidin-4-one (20 mg, 0.08 mmol, 1 eq) and 2-[4-(4-chloro-3-trifluoromethyl-phenoxy)-phenyl]-ethylamine (40 mg, 0.127 mmol, 1.58 eq) were heated in 300 μl of dry pyridine at 150° C. 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 5-100% of 30% MeOH in DCM in 25 column volumes). Solvent from the gathered fractions of appropriate composition was evaporated and obtained was 2-{2-[4-(4-chloro-3-trifluoromethyl-phenoxy)-phenyl]-ethylamino}-5-(6-oxo-1,6-dihydro-pyridin-3-ylmethyl)-1H-pyrimidin-4-one (5.4 mg, yield=11.7%, purity=90%). MS: [M+H]+=517.34. 1H NMR (300 MHz; DMSO-d6) δ/ppm 2.81 (t, J=7.032 Hz, 2H), 3.23 (s, 2H), 3.43-3.53 (m, 2H), 6.24(d, J=9.45 Hz, 1H), 6.36 (br.s., 1H), 7.03-7.14 (m, 3H), 7.20-7.37 (m, 4H), 7.41 (d, J=2.55 Hz, 1H), 7.54 (s, 1H), 7.70 (d, J=8.82 Hz, 1H).
