실험 절차

2-Methylsulfanyl-5-pyrimidin-5-ylmethyl-1H-pyrimidin-4-one (40 mg, 0.171 mmol, 1 eq) and 2-[4-(3-trifluoromethyl-phenoxy)-phenyl]-ethylamine (53 mg, 0.188 mmol, 1.1 eq) were dissolved in dry ethanol (300 μl) and stirred at 120° C. for 6 h. Ethanol was evaporated during the reaction and in the mixture was added pyridine (300 μl) and reaction was stirred for 3 h. Pyridine was evaporated and 0.5 ml of EtOH was added. Precipitate was formed and it was starting material. Mother liquor was evaporated and purified via Biotage SP-1 Snap Si 10 g in the gradient of MeOH in DCM: 1% for 1 CV, 1-5% for 18 CV; 5-10% for 20 CV. The appropriate fractions were combined and evaporated in vacuo to give the required product which was not pure enough and it was sent to HPLC/MS Purification. After HPLC/MS purification combined fractions of desired product were collected and put on lyophilisation to obtain 5-pyrimidin-5-ylmethyl-2-{2-[4-(3-trifluoromethyl-phenoxy)-phenyl]-ethylamino}-1H-pyrimidin-4-one (0.0087 mmol; yield: 5.1%, HPLC-MS/UV: [M+H]+=468.45; rt: 10.90 min; purity: 94.9%). 1H NMR (300 MHz; DMSO-d6) δ/ppm 2.78 (t, J=7.17 Hz, 2H), 3.41-3.47 (m, 2H), 3.50 (s, 2H), 6.99 (d, J=8.40 Hz, 2H), 7.22 (d, J=8.34 Hz, 1H), 7.24-7.31 (m, 3H), 7.44 (d, J=7.82 Hz, 1H), 7.56 (s, J=7.92 Hz, 1H), 7.60 (s, 1H), 8.66 (s, 2H), 8.94 (s, 1H)
