Reaction Steps

2-[4-(4-chloro-3-trifluoromethyl-phenoxy)-phenyl]-ethylamine (0.317 mmol, 1.00 eq) and 2-methylsulfanyl-5-pyridazin-4-ylmethyl-1H-pyrimidin-4-one (0.341 mmol, 1.01 eq) were dissolved in dry ethanol (300 μL) and stirred at 150° C. overnight. Solvent was evaporated and crude product was purified on Biotage SP1 Snap Si 10; 15 ml/min in the gradient of MeOH in DCM: 0-7% in 15 CV. 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-pyridazin-4-ylmethyl-1H-pyrimidin-4-one (0.135 mmol, yield: 43%, UPLC-MS/UV:[M+H]+=502.30; rt: 1.07 mins; purity: 95%). 1H NMR (300 MHz; CDCl3) δ/ppm 1.42 (s, 1H), 2.89 (t, J=7.33, 2H), 3.55-3.60 (m, 2H), 3.62 (s, 2H), 6.99 (dd, J=8.40, J=10.08, 2H), 7.01 (dd, J=9.07 J=3.02, 1H), 7.16-7.28 (m, 3H), 7.35-7.42 (m, 2H), 7.62-7.70 (m, 1H), 8.94 (dd, J=5.42, J=0.95, 1H), 9.09-9.12 (m, 1H)
