Reaction Steps

2-[4-(4-chloro-3-trifluoromethyl-phenoxy)-phenyl]-ethylamine (0.380 mmol, 1.00 eq) and 2-methylsulfanyl-5-(2-oxo-1,2-dihydro-pyrimidin-5-ylmethyl)-1H-pyrimidin-4-one (0.240 mmol, 0.63 eq) were dissolved in dry pyridine (300 μL) and stirred at 150° C. overnight. Solvent was evaporated and crude product was purified on Biotage SP 1 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 2-{2-[4-(4-chloro-3-trifluoromethyl-phenoxy)-phenyl]ethylamino}-5-(2-oxo-1,2-dihydro-pyrimidin-5-ylmethyl)-1H-pyrimidin-4-one (0.041 mmol, yield: 11%, HPLC-MS/UV:[M+H]+=518.047; rt: 10.97 mins; purity: 85%). 1H NMR (300 MHz; CDCl3) δ/ppm 2.80 (t, J=6.50, 2H), 3.19-3.22 (m, 2H), 3.41-3.52 (m, 2H), 5.39 (br.s., 1H), 6.33-6.64 (m, 1H), 6.99-7.10 (m, 2H), 7.22 (dd, J=9.24, J=3.42, 1H), 7.26-7.32 (m, 2H), 7.38-7.43 (m, 1H), 7.58-7.72 (m, 2H), 8.11 (br.s., 1H), 10.93 (br.s., 1H)
