2-[4-(5-trifluoromethyl-pyridin-2-yloxy)-phenyl]-ethylamine (0.354 mmol, 1 eq) and 5-(2-methyl-pyrimidin-5-ylmethyl)-2-methylsulfanyl-1H-pyrimidin-4-one (0.322 mmol, 0.9 eq) were dissolved in dry ethanol (300 μL) and stirred at 125° C. for 50 hours. Solvent was evaporated and crude product was purified on Biotage SP1 Snap Si 10; 15 ml/min in the gradient of MeOH in DCM: 0-10% in 25CV. The appropriate fractions were combined and evaporated in vacuo to give the required product 5-(2-methyl-pyrimidin-5-ylmethyl)-2-{2-[4-(5-trifluoromethyl-pyridin-2-yloxy)phenyl]ethylamino}-1H-pyrimidin-4-one (0.064 mmol, yield: 18%, HPLC-MS/UV:[M+H]+=483.37; rt: 0.89 mins; purity: 93%). 1H NMR (300 MHz; CDCl3) δ/ppm 2.66 (s, 3H), 2.93 (t, J=7.39, 2H), 3.54 (s, 2H), 3.60-3.70 (m, 2H), 5.39 (br.s., 1H), 7.01 (d, J=8.69, 1H), 7.08 (d, J=8.50 2H), 7.27-7.31 (m, 2H), 7.66 (s, 1H), 7.89 (dd, J=9.58, J=2.73, 1H), 8.36-8.42 (m, 1H), 8.51 (s, 2H), 11.21 (br.s., 1H)
