Reaction Steps

A mixture of 4-chloro-2-(3-chlorophenyl)-6-ethylpyrimidine (0.150 g, 0.59 mmol) and 2-(4-aminophenyl)acetamide (0.107 g, 0.71 mmol) and 4M HCl in dioxane (2 drops) in acetic acid (3 mL) was heated for 2 h at 108° C. After this time, the mixture was cooled to rt, neutralized with saturated NaHCO3, extracted with EtOAc, dried (Na2SO4), filtered, and concentrated. The residue was purified by silica gel chromatography eluting with methylene chloride and methanol to afford the title compound (0.135 g, 62%) as a white solid. MW=366.84. 1H NMR (DMSO-d6, 500 MHz) δ 9.57 (s, 1H), 8.33-8.29 (m, 2H), 7.64 (d, J=8.4 Hz, 2H), 7.58-7.54 (m, 2H), 7.43 (br s, 1H), 7.27 (d, J=8.5 Hz, 2H), 6.86 (br s, 1H), 6.59 (s, 1H), 3.35 (s, 2H), 2.67 (q, J=7.6 Hz, 2H), 1.26 (t, J=7.6 Hz, 3H); ESI MS m/z 367 [M+H]+.
